Critical Care Nursing Practice Questions

Correct Answer: C

Rationale: The correct answer is C: Safety. In hyperactive delirium, the patient may be agitated, disoriented, and at risk of harm. Safety is the priority to prevent falls or injury. Comfort (A) is important but secondary to safety in this case. Nourishment (B) can wait until safety is ensured. Sedation (D) may be considered but only after safety measures are in place.

Correct Answer: B

Rationale: The correct answer is B because peritoneal dialysis utilizes the patient's own semipermeable membrane, the peritoneal membrane, as the filtration surface. This allows for the exchange of waste products and excess fluids without the need for external dialysis equipment. Choice A is incorrect as peritoneal dialysis can be used for both acute and chronic kidney injury. Choice C is incorrect as peritoneal dialysis can help manage drug overdose and electrolyte imbalances. Choice D is incorrect as peritoneal dialysis can be used in cases of water intoxication to help remove excess fluids.

Correct Answer: A

Rationale: The correct answer is A because this patient had a complex surgery with complications, requiring long-term care and loss of a significant other, which can impact their emotional well-being and support system. This can lead to decreased functional status and quality of life. Choice B is incorrect as the patient has support from a spouse and manages health care independently, indicating a good support system. Choice C is incorrect as the patient is cognitively intact and social, which suggests a good quality of life. Choice D is incorrect as the patient had a less complex procedure, well-managed diabetes, and was living independently, which indicates a lower risk for decreased functional status and quality of life compared to choice A.

Correct Answer: C

Rationale: The correct answer is C: Taking all asthma medications as prescribed. This is the most appropriate action to prevent exacerbation of asthma symptoms. By taking medications as prescribed, the patient can effectively manage and control their asthma, reducing the risk of exacerbation. Following the prescribed medication regimen helps to keep inflammation in check and maintain airway function. Choice A is incorrect because while follow-up appointments are important, they do not directly prevent exacerbation. Choice B is incorrect as limiting activity may not address the underlying cause of exacerbation. Choice D is incorrect as taking medications on an "as needed" basis may not provide consistent control of asthma symptoms, leading to potential exacerbation.

Correct Answer: C

Rationale: The correct answer is C: Administer the dose as prescribed. Verapamil is a calcium channel blocker used to treat atrial flutter. The vital signs obtained are within normal range for this medication. A heart rate of 92 and blood pressure of 110/76 are not contraindications for administering verapamil. Option A is incorrect as calcium gluconate is not indicated in this situation. Option B is incorrect because the vital signs are stable and do not warrant withholding the medication. Option D is incorrect as there is no need to delay the administration of verapamil based on the vital signs provided.
