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 C
A. Cleansing the skin with a pH-balanced soap
B. Lubricating the skin with a moisturizing cream
C. Massaging reddened areas of the skin
D. Using absorbent garments for incontinence
The nurse should avoid massaging reddened areas of the skin because it can result in damage to capillary beds and lead to tissue necrosis. Answers A, B, and D are appropriate interventions for the client at risk for pressure ulcers; therefore, they are incorrect.
The Correct Answer is Option A
A. A 42-year-old with dyspnea and chest asymmetry
B. A 17-year-old with a fractured arm
C. A 4-year-old with facial lacerations
D. A 30-year-old with blunt abdominal trauma
Following the ABCDs of basic emergency care, the client with dyspnea and asymmetrical chest should be cared for first because these symptoms are associated with flail chest. Answer D is incorrect because he should be cared for second because of the likelihood of organ damage and bleeding. Answer B is incorrect because he should be cared for after the client with abdominal trauma. Answer C is incorrect because he should receive care last because his injuries are less severe.
The Correct Answer is Option B
A. 2–4 mm
B. 3–5 mm
C. 6–8 mm
D. 7–9 mm
The normal pupil diameter is between 3 and 5 mm in size. Answers A, C, and D are not normal pupil diameters; therefore, they are incorrect.
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.
The Correct Answer is Option B
A. Clear liquids the day before the test
B. Nothing by mouth the night before the test
C. High-fat meal two hours before the test
D. Asking the client to bring a sputum sample with her for analysis
The only preparation for H. pylori urea breath test is NPO after midnight. In this test, the client drinks a carbon-enriched urea liquid and then CO2 is measured for H. pylori. Answers A, C, and D are not part of the preparation for an H. pylori urea breath test, so they are incorrect options.
The Correct Answer is True
The Correct Answer is Option B
A. The nurse prepares an IV of D10W.
B. The nurse prepares to administer insulin IV.
C. The nurse obtains NPH insulin for administration.
D. The nurse inserts a Foley catheter.
The client with a blood glucose of 545 mg/dl is in metabolic acidosis. An IV with insulin will be ordered. Insulin takes the glucose into the cells hence, reducing the glucose levels. Answer A is incorrect because D10W will increase the glucose level and potentiate the client’s condition. Answer C is incorrect because regular insulin will be ordered, not NPH, which is long-acting. Answer D is incorrect because although a Foley catheter might be ordered, it is not necessary for the improvement of the client’s condition.
The Correct Answer is Option B
A. Test the corneal reflexes.
B. Test the 6 cardinal positions of gaze.
C. Test visual acuity, using a Snellen eye chart.
D. Test sensory function by asking the client to close the eyes and then lightly touching the forehead, cheeks, and chin.
Testing the 6 cardinal positions of gaze (diagnostic positions test) is done to assess for muscle weakness in the eyes. The client is asked to hold the head steady, and then to follow the movement of an object through the positions of gaze. The client should follow the object in a parallel manner with the 2 eyes. A Snellen eye chart assesses visual acuity and cranial nerve II (optic). Testing sensory function by having the client close his or her eyes and then lightly touching areas of the face and testing the corneal reflexes assess cranial nerve V (trigeminal).
The Correct Answer is Option B
A. Begin an IV of normal saline at keep-open rate
B. Continue the magnesium sulfate as ordered
C. Contact the doctor immediately
D. Prepare for an emergency delivery
The therapeutic range for magnesium sulfate is 4.0–9.6 meq/L; therefore, with a magnesium level of 6.3meq/L, the nurse should continue the infusion. Answers A, C, and D indicate that the nurse believes the level to be toxic. This is an incorrect conclusion, making these answers incorrect.
The Correct Answer is Option D
A. Inserting a Foley catheter
B. Discontinuing a nasogastric tube
C. Obtaining a sputum specimen
D. Starting a blood transfusion
The LPN can be assigned to insert Foley and French urinary catheters, discontinue Levin and gavage gastric tubes, and obtain all types of specimens. Administering a blood transfusion is outside the scope of practice of an LPN. Another practice outside of an LPN's scope is administering a controlled medication such as Morphine. LPNs can witness the commencement of blood transfusion and witness the administration of controlled medications.
The Correct Answer is Option D
A. 12 months
B. 18 months
C. 24 months
D. 30 months
Most children have all their primary teeth by age 30 months. Answers A, B, and C are incorrect because tooth eruption is not complete.
The Correct Answer is Option A
A. Kayexalate (sodium polystyrene sulfonate)
B. K-Dur (potassium chloride)
C. Cephulac (lactulose)
D. PhosLo (calcium acetate)
Kayexalate (sodium polystyrene sulfonate) is administered to lower potassium levels in the client with hyperkalemia. K-Dur is used for the client with hypokalemia; therefore, answer B is incorrect. Lactulose is used to lower ammonia levels in the client with liver disease; therefore, answer C is incorrect. PhosLo is used to lower phosphorus levels in the client with renal disease; therefore, Answer D is incorrect.
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 C
A. Walk 20 minutes a day to maintain muscle strength
B. Expect a reddish discoloration of her urine
C. Notify the doctor of a sore throat or fever
D. Eat smaller, more frequent meals
Cytoxan is an immunosuppressive drug; therefore, the client should notify the doctor of symptoms associated with infection. Answers A and D are not associated with the use of Cytoxan; therefore, they are incorrect. The client taking Cytoxan can experience hemorrhagic cystitis due to inadequate fluid intake, but it is not an expected finding; therefore, answer B is incorrect.
The Correct Answer is Option C
A. A defect in the cochlea
B. A defect in cranial nerve VIII
C. A physical obstruction to the transmission of sound waves
D. A defect in the sensory fibers that lead to the cerebral cortex
A conductive hearing loss occurs as a result of a physical obstruction to the transmission of sound waves. A sensorineural hearing loss occurs as a result of a pathological process in the inner ear, a defect in cranial nerve VIII, or a defect of the sensory fibers that lead to the cerebral cortex.
The Correct Answer is Option B
A. Initiate the IV line without the use of a pump.
B. Contact the electrical maintenance department for assistance.
C. Plug in the pump cord in the available plug above the room sink.
D. Use an extension cord from the nurses’ lounge for the pump plug.
Electrical equipment must be maintained in good working order and should be grounded; otherwise, it presents a physical hazard. An IV line that contains a dose of potassium chloride should be administered by an infusion pump. The nurse needs to use hospital resources for assistance. A regular extension cord should not be used because it poses a risk for fire. Use of electrical appliances near a sink also presents a hazard.
The Correct Answer is Option A
Total Volume / Time x Drip Factor = 1000 mL / 24 hours x 15drops/mL = 625 drops/hour
625drops/hour x 1hour/60minutes = 10.4166667 = 10 drops/minute (rounded off to a whole number)
The Correct Answer is Option D
A. Culture
B. VDRL
C. RPR
D. FTA-ABS
The fluorescent treponemal antibody test (FTA-ABS) is most diagnostic for syphilis. Answer A is incorrect because a culture of the discharge is used to diagnose gonorrhea, not syphilis. Answers B and C are incorrect because they are screening tests and are not as diagnostic as the FTA-ABS is.
The Correct Answer is Option D
A. Take half the dose to control the problem
B. Take cough medication to control the problem
C. Stop the medication
D. Report the problem to the doctor
A hacking cough is a common side effect and should be reported to the doctor. The client should not be told to half the dose because this can result in an elevated blood pressure, so answer A is incorrect. Answer B is incorrect because taking a cough medication will mask the symptom of a possible allergic reaction. Answer C is incorrect because, although the client stops taking the medication, this answer states that the client can report the finding to the doctor at the time of the scheduled visit. She should report this finding immediately.
The Correct Answer is Option B
A. Urinary output
B. Respirations
C. Temperature
D. Verbal responsiveness
Barbiturate overdose results in central nervous system depression, which leads to respiratory failure. Answers A and C are important to the client’s overall condition but are not specific to the question, so they are incorrect. The use of barbiturates results in slow, slurred speech, so answer D is expected, and therefore incorrect
