Nursing Elites

1. A 6-month-old infant is prescribed digoxin for the treatment of congestive heart failure. Which observation by the practical nurse (PN) warrants immediate intervention for signs of digoxin toxicity?

• A. Apical heart rate of 60 beats/min
• B. Sweating across the forehead
• C. Poor sucking effort
• D. Respiratory rate of 30 breaths/min

Correct answer: A

Rationale: A heart rate of 60 beats/min for a 6-month-old infant warrants immediate intervention as it falls below the normal range. The normal heart rate for a 6-month-old is 80 to 150 beats/min when awake, and a rate of 70 beats/min while sleeping is considered within normal limits. Bradycardia (heart rate <60 beats/min) in infants can be a sign of digoxin toxicity, necessitating prompt evaluation and intervention to prevent adverse effects. Sweating across the forehead (Choice B) is a non-specific symptom and may not directly indicate digoxin toxicity. Poor sucking effort (Choice C) and a respiratory rate of 30 breaths/min (Choice D) are not typically associated with digoxin toxicity and do not require immediate intervention in the context of this question.

2. A client has a prescription for heparin 1,000 units IV STAT. Several pre-filled syringes of low molecular weight heparin are available in the client's medication drawer. Which action should the nurse implement?

• A. Dilute the available heparin in 250ml of normal saline solution prior to IV administration
• B. Advise the pharmacy on the need to deliver a vial of heparin to the nursing unit immediately
• C. Calculate and administer the equivalent dose of the available low molecular weight heparin
• D. Request a prescription to change the route of administration and use the available heparin

Correct answer: B

Rationale: In this scenario, the nurse should contact the pharmacy to obtain the correct heparin formulation as the prescription calls for heparin 1,000 units IV STAT. Low molecular weight heparin is not the same as unfractionated heparin, and therefore, the nurse should not administer the available low molecular weight heparin without first obtaining the correct medication. Diluting the available heparin, calculating an equivalent dose, or changing the route of administration would not address the discrepancy between the prescribed heparin and the available low molecular weight heparin.

3. When a client with hypertension is prescribed losartan, what potential side effect should the nurse monitor for?

• A. Hyperkalemia
• B. Dry cough
• C. Bradycardia
• D. Headache

Correct answer: B

Rationale: The correct answer is B: Dry cough. Losartan, an angiotensin II receptor blocker, can lead to a dry cough as a potential side effect. This occurs due to the drug's effect on the bradykinin pathway in the lungs. Monitoring for a dry cough is essential as it may indicate the need for further evaluation or medication adjustment to manage this adverse reaction.

4. A client with osteoporosis is prescribed raloxifene. The nurse should reinforce which instruction?

• A. Take this medication at the same time each day.
• B. Take this medication with a full glass of water.
• C. Take this medication on an empty stomach.
• D. Take this medication immediately after a meal.

Correct answer: A

Rationale: The correct instruction for a client prescribed raloxifene, a medication used for osteoporosis, is to take it at the same time each day. This consistency helps maintain steady blood levels of the medication, enhancing its effectiveness in managing the condition. Choice B is incorrect because raloxifene does not require a full glass of water for administration. Choice C is incorrect as raloxifene should not be taken on an empty stomach. Choice D is incorrect as raloxifene should not be taken immediately after a meal.

5. A client diagnosed with seizures is prescribed phenytoin. Which medication instruction should the practical nurse (PN) reinforce to this client?

• A. Maintain consistent sodium intake.
• B. Use sunscreen when outdoors.
• C. Return for monthly urinalysis.
• D. Brush and floss teeth daily.

Correct answer: D

Rationale: The correct answer is to reinforce the instruction to brush and floss teeth daily. Phenytoin therapy can lead to gingival hyperplasia (gum disease), which can be prevented by maintaining good oral hygiene practices such as brushing and flossing daily. Choices A, B, and C are incorrect because they are not directly related to the side effects or management of phenytoin therapy. Maintaining consistent sodium intake is not a specific concern with phenytoin. Using sunscreen when outdoors is important to prevent sunburn but is not directly related to phenytoin therapy. Returning for monthly urinalysis may be necessary for other medications, but it is not specifically required for monitoring phenytoin therapy.
