1. A healthcare provider is assisting in the care of a client who is having central venous pressure (CVP) measurements taken. The healthcare provider should assist by placing the bed in which position for the reading?
- A. Flat
- B. Semi-Fowler's
- C. Trendelenburg
- D. Reverse Trendelenburg
Correct answer: A
Rationale: Central venous pressure (CVP) measurements are most accurate when the client is lying flat, as this allows for a consistent baseline. Placing the bed flat ensures that the hydrostatic pressure within the vena cava is not affected by the client's position, providing a more precise reading. Choice B (Semi-Fowler's) elevates the head of the bed at a 30-45 degree angle, which could affect the accuracy of CVP readings. Choices C (Trendelenburg) and D (Reverse Trendelenburg) involve extreme positions that would not be suitable for obtaining accurate CVP measurements.
2. A client has a new prescription for enalapril. Which of the following instructions should the nurse include?
- A. Monitor for a dry cough.
- B. Take the medication at bedtime.
- C. Avoid consuming grapefruit juice.
- D. Take the medication with food.
Correct answer: A
Rationale: The correct answer is A: Monitor for a dry cough. When a client is prescribed enalapril, it is important to monitor for a dry cough because it can be a side effect that indicates a potential issue like angioedema. This side effect needs close attention as it may require discontinuation of the medication to prevent further complications. Choices B, C, and D are incorrect because enalapril does not need to be taken at bedtime, does not interact with grapefruit juice, and can be taken without regard to meals.
3. The nurse is assisting in the care of a client experiencing an acute myocardial infarction (MI). Which medication would the nurse expect to be administered to help reduce myocardial oxygen demand?
- A. Aspirin
- B. Morphine
- C. Atropine
- D. Lidocaine
Correct answer: B
Rationale: In the context of an acute myocardial infarction (MI), morphine is administered to relieve pain and reduce myocardial oxygen demand. By alleviating pain and anxiety, morphine helps reduce oxygen demand on the heart, which is beneficial in the setting of an MI. Aspirin, commonly used for its antiplatelet effects, helps inhibit platelet aggregation and is crucial in the management of MI to prevent further clot formation. Atropine is a medication used to treat symptomatic bradycardia by increasing heart rate, not commonly indicated in the management of acute MI. Lidocaine is used for ventricular dysrhythmias and is not typically given to reduce myocardial oxygen demand in an acute MI scenario.
4. A client who had a myocardial infarction (MI) two days ago reports chest pain radiating to the left arm. What should the nurse do immediately?
- A. Administer morphine
- B. Obtain an electrocardiogram (ECG)
- C. Apply oxygen via nasal cannula
- D. Administer sublingual nitroglycerin
Correct answer: B
Rationale: Obtaining an ECG is crucial in this situation because it helps in assessing for potential complications, such as a recurrent MI or ongoing ischemia. This diagnostic test provides valuable information to guide further interventions and treatment. Administering morphine, oxygen, or nitroglycerin may be necessary but obtaining an ECG takes precedence to evaluate the cardiac status and determine the appropriate course of action. Administering morphine without assessing the current cardiac status through an ECG can mask important diagnostic clues. Applying oxygen and administering nitroglycerin are supportive measures that can follow the ECG to address potential hypoxia and ischemic pain relief, respectively.
5. A client with heart failure is prescribed an angiotensin-converting enzyme (ACE) inhibitor. What instruction should the nurse reinforce to the client?
- A. Take the medication at bedtime.
- B. Report a persistent dry cough.
- C. Increase potassium-rich foods in the diet.
- D. Avoid taking the medication with meals.
Correct answer: B
Rationale: The correct answer is B. A persistent dry cough is a common side effect of ACE inhibitors and should be reported to the healthcare provider. This symptom can indicate a potential issue with the medication that may require adjustment or discontinuation. Choices A, C, and D are incorrect. Taking the medication at bedtime or with meals is not a specific instruction for ACE inhibitors. Increasing potassium-rich foods in the diet is not directly related to ACE inhibitor therapy and may not be suitable for all patients.
