The nurse is taking the blood pressure measurement of a client with Parkinson's disease. Which information in the client's admission assessment is relevant to the nurse's plan for taking the blood pressure reading?
- A. Frequent syncope
- B. Muscle rigidity
- C. Gait instability
- D. Fine motor tremors
Correct Answer: A
Rationale: The correct answer is A: 'Frequent syncope.' Orthostatic hypotension, common in Parkinson's disease, often causes syncope (fainting) when blood pressure drops upon standing. This information is critical for planning safe blood pressure measurements, ensuring readings are taken in both lying and standing positions to assess for sudden drops in pressure. Muscle rigidity, tremors, or gait instability are important symptoms in Parkinson's disease but are not directly related to blood pressure assessment.

Which strategy should the nurse implement when teaching a client with low literacy about a new diagnosis of hypertension?
- A. Provide a detailed handout with complex terms
- B. Use simple language and visual aids
- C. Encourage the client to research the diagnosis online
- D. Incorporate medical jargon to explain the condition
Correct Answer: B
Rationale: The correct strategy for teaching a client with low literacy about a new diagnosis of hypertension is to use simple language and visual aids. This approach helps ensure better understanding of the diagnosis and treatment plan by making the information clear and accessible. Providing a detailed handout with complex terms (Choice A) would not be suitable as it may confuse the client further. Encouraging the client to research the diagnosis online (Choice C) could lead to misinformation and overwhelm the client with information they may not understand. Incorporating medical jargon to explain the condition (Choice D) would not be helpful for a client with low literacy as it may complicate rather than clarify the information.
A client with hyperkalemia is receiving insulin and glucose. Which laboratory value should the nurse monitor closely?
- A. Monitor the client's blood glucose level.
- B. Monitor the client's sodium level.
- C. Monitor the client's calcium level.
- D. Monitor the client's potassium level.
Correct Answer: D
Rationale: The correct answer is to monitor the client's potassium level. When administering insulin and glucose in hyperkalemia, the aim is to shift potassium from the bloodstream into the cells, lowering elevated levels. Therefore, monitoring potassium levels closely is essential to prevent hypokalemia or further complications. Monitoring blood glucose levels (Choice A) is important but not the priority in this scenario. Monitoring sodium (Choice B) and calcium levels (Choice C) is not directly related to the treatment of hyperkalemia with insulin and glucose.
A client with a history of coronary artery disease is experiencing chest pain. What is the nurse's first action?
- A. Administer sublingual nitroglycerin
- B. Obtain a 12-lead electrocardiogram
- C. Call the healthcare provider
- D. Check the client's oxygen saturation
Correct Answer: A
Rationale: The correct answer is A: Administer sublingual nitroglycerin. Sublingual nitroglycerin is the first-line treatment for chest pain related to coronary artery disease. It helps dilate the coronary arteries and improve blood flow to the heart, providing immediate relief from ischemia. Administering nitroglycerin promptly can help alleviate the chest pain and prevent further complications. Obtaining a 12-lead electrocardiogram (Choice B) is important but should not delay the administration of nitroglycerin. Calling the healthcare provider (Choice C) can be done after initiating immediate treatment. Checking the client's oxygen saturation (Choice D) is relevant but not the first action to take in this scenario.
A client at 12 weeks gestation is admitted to the antepartum unit with a diagnosis of hyperemesis gravidarum. Which action is most important for the nurse to implement?
- A. Provide emotional support
- B. Monitor daily weight
- C. Encourage small frequent meals
- D. Initiate prescribed intravenous fluids
Correct Answer: D
Rationale: Hyperemesis gravidarum, characterized by severe nausea and vomiting, leads to dehydration and electrolyte imbalances. The priority intervention is initiating IV fluids to correct these imbalances. Providing emotional support is important for the client's well-being, but addressing fluid and electrolyte imbalances takes precedence. Monitoring daily weight and encouraging small frequent meals are beneficial interventions but are not the priority when managing hyperemesis gravidarum.
Which medication should the nurse withhold if the client's serum potassium level is 6.2 mEq/L?
- A. Losartan
- B. Spironolactone
- C. Metoprolol
- D. Furosemide
Correct Answer: B
Rationale: The correct answer is B: Spironolactone. Spironolactone is a potassium-sparing diuretic that can lead to hyperkalemia. With potassium levels already elevated at 6.2 mEq/L, withholding Spironolactone is essential to prevent further increase in potassium levels, which could result in dangerous cardiac arrhythmias. Losartan (Choice A) is an angiotensin receptor blocker and does not directly affect potassium levels. Metoprolol (Choice C) is a beta-blocker and also does not impact potassium levels significantly. Furosemide (Choice D) is a loop diuretic that can actually lower potassium levels, so it would not be the medication to withhold in this case.
