1. The healthcare provider is assessing a client with a suspected myocardial infarction. Which finding requires immediate intervention?
- A. Chest pain radiating to the left arm.
- B. Shortness of breath.
- C. Nausea and vomiting.
- D. Diaphoresis.
Correct answer: B
Rationale: Shortness of breath is a critical sign that can indicate heart failure or pulmonary edema, conditions that require immediate intervention in a client with a suspected myocardial infarction. Chest pain radiating to the left arm is a classic symptom of a myocardial infarction but may not necessitate immediate intervention compared to severe shortness of breath. Nausea and vomiting can be present in myocardial infarction but are not as urgent as shortness of breath. Diaphoresis, or sweating, is a common symptom of a myocardial infarction but may not be as immediately concerning as significant shortness of breath.
2. What pathophysiological events occur sequentially in the development of atherosclerosis?
- A. Foam cells release growth factors.
- B. Smooth muscle grows over fatty streaks creating fibrous plaques.
- C. Macrophages consume low-density lipoprotein (LDL) and create foam cells.
- D. Arterial endothelium injury causes inflammation.
Correct answer: D
Rationale: The correct sequence of pathophysiological events in the development of atherosclerosis starts with arterial endothelium injury causing inflammation. This inflammation triggers the formation of foam cells by macrophages consuming low-density lipoprotein (LDL). Subsequently, smooth muscle grows over fatty streaks, creating fibrous plaques. Therefore, option D is the correct answer. Choices A, B, and C are incorrect because they do not reflect the accurate chronological order of events in the pathogenesis of atherosclerosis.
3. The nurse is assessing a client with left-sided heart failure. Which laboratory value is most concerning?
- A. Serum creatinine of 1.5 mg/dL
- B. Serum sodium of 136 mEq/L
- C. Serum potassium of 5.5 mEq/L
- D. Hemoglobin of 12 g/dL
Correct answer: C
Rationale: A serum potassium level of 5.5 mEq/L is most concerning in a client with left-sided heart failure as it indicates hyperkalemia, requiring immediate intervention. Hyperkalemia can lead to life-threatening cardiac arrhythmias, which can exacerbate heart failure. Serum creatinine of 1.5 mg/dL is slightly elevated but not as immediately concerning as hyperkalemia. Serum sodium of 136 mEq/L is within the normal range. Hemoglobin of 12 g/dL is also within the normal range and not directly related to the client's left-sided heart failure.
4. The client has syndrome of inappropriate antidiuretic hormone (SIADH). Which intervention is most appropriate?
- A. Encourage increased fluid intake
- B. Administer hypertonic saline
- C. Monitor for signs of dehydration
- D. Restrict oral fluids
Correct answer: D
Rationale: The correct intervention for a client with syndrome of inappropriate antidiuretic hormone (SIADH) is to restrict oral fluids. This is because SIADH leads to excessive production of antidiuretic hormone, causing water retention and dilutional hyponatremia. By restricting oral fluids, the nurse helps prevent further water retention and imbalance of electrolytes. Encouraging increased fluid intake (Choice A) would exacerbate the condition by further increasing fluid retention. Administering hypertonic saline (Choice B) is not the primary treatment for SIADH, as it may worsen the imbalance. Monitoring for signs of dehydration (Choice C) is not appropriate since SIADH leads to water retention, not dehydration.
5. A patient has begun taking spironolactone (Aldactone) in addition to a thiazide diuretic. With the addition of the spironolactone, the nurse will counsel this patient to
- A. not take a potassium supplement daily.
- B. recognize that abdominal cramping is a common side effect.
- C. report decreased urine output to the provider.
- D. take these medications in the morning.
Correct answer: C
Rationale: When combining a potassium-sparing diuretic like spironolactone with a thiazide diuretic, there is an increased risk of hyperkalemia, especially in patients with poor renal function. Therefore, the patient should be educated to report any decrease in urine output, which could indicate a potential issue with kidney function. Choice A is incorrect because taking additional potassium supplements can further increase the risk of hyperkalemia. Choice B is incorrect as abdominal cramping is not a common side effect of spironolactone. Choice D is incorrect because the timing of medication administration is not directly related to the addition of spironolactone and thiazide diuretic; there is no specific recommendation to take these medications only at bedtime.
