Demo Quiz
Welcome to the Demo Quiz! Below, you will find numerous sample questions. This demo quiz is set up with questions and the question's answer with Answer reason.
The Correct Answer is Option A
A. Constriction of blood flow
B. Immobilization of the joint
C. Formation of a decubitus ulcer
D. Oozing of blood from the wound
Wrapping an elastic bandage on a stump using the circular technique can cause the wrap to act as a tourniquet and restrict blood flow, so a figure eight technique is utilized to prevent this from occurring. Answers B, C, and D are not the primary reasons for use of the figure eight technique, so they are incorrect.
The Correct Answer is Option C
A. Cover the cord with dry, sterile gauze
B. Place the client in high Fowler’s position
C. Push up on the presenting part with an examining finger
D. Begin an IV of normal saline at keep-open rate
The nurse should push on the presenting part to relieve pressure on the cord and facilitate blood flow through the cord. Answer A is incorrect because the sterile gauze should be moist, not dry. Answer B is incorrect because the client should be placed in Trendelenburg position, not high Fowler’s position. Answer D is incorrect because the IV fluid should be rapid, not keep-open rate, to increase hydration and blood flow to the fetus.
The Correct Answer is Option C
A. Insulin
B. Inderal (propanolol)
C. Lasix (furosemide)
D. Valium (diazepam)
Lasix is a non–potassium-sparing diuretic. This drug can potentiate fluid volume deficit. Answer A is incorrect because insulin will force fluid back into the cell and will not increase fluid volume deficit. Answer B is incorrect because Inderal (propanolol) is a beta-blocker used for the treatment of hypertension and cardiac disease. Inderal does not potentiate diuresis. Answer D is incorrect because Valium (diazepam) is a phenothiazine used as an anti-anxiety medication. This drug does not potentiate fluid volume deficit.
The Correct Answer is Option A
A. Rhythmic respirations with periods of apnea
B. Regular rapid and deep, sustained respirations
C. Totally irregular respiration in rhythm and depth
D. Irregular respirations with pauses at the end of inspiration and expiration
Cheyne-Stokes respirations are rhythmic respirations with periods of apnea and can indicate a metabolic dysfunction in the cerebral hemisphere or basal ganglia. Neurogenic hyperventilation is a regular, rapid and deep, sustained respiration that can indicate a dysfunction in the low midbrain and middle pons. Ataxic respirations are totally irregular in rhythm and depth and indicate a dysfunction in the medulla. Apneustic respirations are irregular respirations with pauses at the end of inspiration and expiration and can indicate a dysfunction in the middle or caudal pons.
The Correct Answer is Option C
A. Magnetic resonance imaging
B. Ultrasonography
C. Noncontrast helical computerized tomography
D. X-ray of the kidneys, ureter, and bladder
Noncontrast helical computerized tomography is the most sensitive means for diagnosing renal calculi. Magnetic resonance imaging, ultrasonography, and x-ray of the kidneys, ureters, and bladder are not as sensitive; therefore, answers A, B, and D are incorrect.
The Correct Answer is Option B
A. Phalen’s maneuver
B. Tinel’s sign
C. Chevotsky’s sign
D. Turner’s sign
This test is measured as described and can result in pain and a tingling sensation if the client has carpal tunnel syndrome (CTS). Answer A is incorrect because it is a test in which the client is asked to place the back of the hands together and flex the wrist at the same time causing pain. Answers C and D are exams not related to CTS, so they are incorrect.
The Correct Answer is Option B
A. Phosphorus 2.5 mEq/L
B. Potassium 1.8 mEq/L
C. Calcium 9.4 mg/dl
D. Magnesium 2.4 mEq/L
The client taking furosemide is at risk for developing hypokalemia (decreased potassium) because this drug is a non–potassium-sparing diuretic. A potassium level of 1.8 is extremely low and might result in cardiac dysrhythmias. Answers A, C, and D are incorrect because the levels noted in the question are within normal levels.
The Correct Answer is Option B
A. The nurse offers extra blankets.
B. The nurse places a tracheostomy tube at the bedside.
C. The nurse insists that the client refrain from talking.
D. The nurse administers pain medication every four hours.
The thyroid is located anterior to the trachea; therefore, laryngeal stridor and airway obstruction is a risk following a thyroidectomy. Answer A is incorrect because this action is not necessary. The need for extra blankets is associated with hypothyroidism, but is not directly associated with thyroid surgery. Answer C is incorrect because the client can talk. Answer D is incorrect because pain medication should be offered as needed, not every four hours.
The Correct Answer is Option C
Change 1 g to milligrams, knowing that 1000 mg =1 g.
Also, when converting from grams to milligrams (larger to smaller), move the decimal point three places to the right: 1 g = 1000 mg.
Next, use the formula for calculating the correct dose.
Formula: Desired / Available x Tablet = 1000 mg / 500 mg = 2 tablets
The Correct Answer is Option C
A. Polydipsia and bradycardia
B. Euphoria and polyuria
C. Muscle weakness and irritability
D. Ringing in the ears and blurred vision
Other symptoms of SIADH include loss of thirst, tachycardia, hostility, and decreased urinary output. This makes Answers A and B incorrect. The answer in D is not associated with SIADH, so it is incorrect.
The Correct Answer is Option B
A. Check the client’s temperature.
B. Isolate the client in a private room.
C. Check a complete set of vital signs
D. Contact the primary health care provider.
The nurse should suspect the potential for Ebola virus disease (EVD) because of the client’s recent travel to Nigeria. The nurse needs to consider the symptoms that the client is reporting, and clients who meet the exposure criteria should be isolated in a private room before other treatment measures are taken. Exposure criteria include a fever reported at home or in the ED of 38.0° C (100.4° F) or headache, fatigue, weakness, muscle pain, vomiting, diarrhea, abdominal pain, or signs of bleeding.
This client is reporting a fever and is showing other signs of EVD, and therefore should be isolated. After isolating the client, it would be acceptable to then collect further data and notify the primary health care provider and other state and local authorities of the client’s signs and symptoms
The Correct Answer is Option D
A. Eliminates the neurotransmitter acetylcholine
B. Increases the perception of external stimuli
C. Decreases levels of cortisol from the adrenal cortex
D. Produces a seizure that temporarily alters brain chemicals
Electroconvulsive therapy produces a tonic-clonic seizure that temporarily increases brain chemicals, serotonin, dopamine, and norepinephrine. Answers A, B, and C are not true statements; therefore, they are incorrect.
The Correct Answer is Option C
A. Stabilize clots in the vascular system
B. Decrease the chance of a blood reaction
C. Eliminate iron excess
D. Boost oxygen delivery to the cells
A chelating agent such as deferoxamine (Desferal) is given to eliminate excess iron. The answers in A, B, and D are not the action of chelating agents, so they are incorrect.
The Correct Answer is Option A
A. After a shower or bath
B. While standing to void
C. After having a bowel movement
D. While lying in bed before arising
The nurse needs to teach the client how to perform a TSE. The nurse should instruct the client to perform the exam on the same day each month. The nurse should also instruct the client that the best time to perform a TSE is after a shower or bath when the hands are warm and soapy and the scrotum is warm. Palpation is easier and the client will be better able to identify any abnormalities. The client would stand to perform the exam, but it would be difficult to perform the exam while voiding. Having a bowel movement is unrelated to performing a TSE.
The Correct Answer is Option C
A. Constipation
B. White blood cell count of 14,000
C. Amylase of 460
D. Potassium of 3.1 mEq/L
Amylase and lipase are reliable tests used for pancreatitis diagnosis. The answers in A, B, and D are not directly related to the pancreas and not diagnostic, so they are incorrect.
The Correct Answer is Option A
A. Propylthiouracil (PTU)
B. Fludrocortisone (Florinef)
C. Levothyroxine (Synthyroid)
D. Glipizide (Glucotrol)
Propylthiouracil (PTU) is an antithyroid medication. Answer B is incorrect because this is a cortisone preparation. Answer C is incorrect because this drug is used for hypothyroidism. Answer D is incorrect because this drug is used to treat diabetes.
The Correct Answer is Option C
A. Weight loss
B. Decreased appetite
C. Hirsutism
D. Integumentary bronzing
Notice that the testing strategy “odd item out” can be used in this question. Answers A, B, and D are symptoms of Addison’s disease. Answer C is the answer that is different from the rest. Hirsutism, or facial hair, is a side effect of cortisone therapy.
The Correct Answer is Option B
A. Place a tourniquet proximal to the laceration
B. Elevate the leg above the level of the heart
C. Cover the laceration and apply an ice compress
D. Apply pressure to the femoral artery
If bleeding does not subside with direct pressure, the nurse should elevate the extremity above the level of the heart. Answers A and D are done only if other measures are ineffective, so they are incorrect. Answer C would slow the bleeding, but will not stop it, so it’s incorrect.
The Correct Answer is Option C
A. Clamp the tubing for 15 minutes every hour
B. Irrigate the tubing with normal saline to remove clots
C. Avoid clamping or kinking the tubing
D. Suspend the tubing above the level of the abdomen
The nurse should avoid clamping or kinking the nephrostomy because urine would be retained in the kidney. Answer A is incorrect because the tubing should not be clamped. Answer B is incorrect because the tubing should not be irrigated because it would damage the renal tissue. Answer D is incorrect because suspending the tubing would cause urine to be retained in the kidney.
The Correct Answer is Option C
A. Anorexia
B. Difficulty swallowing
C. Hirsutism
D. Hot flashes
Hirsutism is facial hair. This is associated with hypersecretion of cortisol. Answers A, B, and D are not associated with Cushing’s disease.
