1. The practical nurse (PN) is obtaining the medical history of a client starting a new prescription for conjugated estrogens PO daily. Which medical condition is not treated by this medication?
- A. Menopausal symptoms
- B. Prostatic cancer
- C. Thromboembolic diseases
- D. Abnormal uterine bleeding
Correct answer: C
Rationale: Conjugated estrogens, such as Premarin, are not used in the treatment of thromboembolic diseases. These medications are contraindicated in conditions predisposing to thromboembolic diseases due to their association with an increased risk of thromboembolism, stroke, pulmonary embolism, and myocardial infarction. Choices A, B, and D are incorrect because conjugated estrogens are commonly prescribed for managing menopausal symptoms, abnormal uterine bleeding, and certain hormone-responsive cancers, but not for thromboembolic diseases.
2. A client has been prescribed losartan. Which change in data indicates to the practical nurse (PN) that the desired effect of this medication has been achieved?
- A. Dependent edema reduced from +3 to +1.
- B. Serum HDL increased from 35 to 55 mg/dL.
- C. Pulse rate reduced from 150 to 90 beats/min.
- D. Blood pressure reduced from 160/90 to 130/80 mm Hg.
Correct answer: D
Rationale: The correct answer is D. Losartan is prescribed for the treatment of hypertension. The desired effect of losartan is to reduce blood pressure. Therefore, a reduction in blood pressure from 160/90 to 130/80 mm Hg indicates that the desired effect of the medication has been achieved. Choices A, B, and C are not specific effects of losartan and do not directly relate to the expected outcomes of this medication. Dependent edema, serum HDL levels, and pulse rate are not typically influenced by losartan, making choices A, B, and C incorrect.
3. 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.
4. A client who takes metformin for diabetes mellitus type 2 is nothing by mouth (NPO) for surgery. What pre-op prescription should the practical nurse (PN) anticipate for this client's glucose management?
- A. NPO except for metformin and regular snacks
- B. NPO except for oral antidiabetic agent
- C. Novolin-N insulin subcutaneously twice daily
- D. Regular insulin subcutaneously per sliding scale
Correct answer: D
Rationale: When a client taking metformin for diabetes mellitus type 2 is NPO for surgery, it is crucial to manage their glucose levels effectively. The best approach in this situation is to prescribe regular insulin subcutaneously according to a sliding scale based on the client's blood glucose levels. This method allows for precise adjustment of insulin doses to maintain blood glucose within the target range while the client is unable to take oral medications. Choices A and B are incorrect because metformin is typically held when a client is NPO, and oral antidiabetic agents may not provide sufficient glucose control. Choice C is incorrect as Novolin-N insulin given twice daily may not offer the flexibility needed for glucose management in a surgical setting where the client's intake is restricted.
5. A client with a history of heart failure is prescribed carvedilol. The nurse should monitor the client for which adverse effect?
- A. Dizziness upon standing
- B. Weight loss
- C. Bradycardia
- D. Hypotension
Correct answer: D
Rationale: The correct answer is D: Hypotension. Carvedilol, a beta-blocker, can lead to hypotension by blocking the effects of adrenaline, which can cause blood vessels to dilate and reduce blood pressure. While dizziness upon standing is a potential adverse effect of carvedilol, it is more specifically related to orthostatic hypotension, which is a form of hypotension that occurs when a person stands up from a sitting or lying position. Weight loss and bradycardia are not typically associated with carvedilol use. Therefore, the nurse should primarily monitor for hypotension in a client taking carvedilol.
