Critical Care Nursing NCLEX Questions

Correct Answer: B

Rationale: The elevated BUN and creatinine levels with a normal BUN/creatinine ratio indicate impaired kidney function. This pattern is commonly seen in acute kidney injury, such as acute tubular necrosis (ATN). In ATN, there is damage to the renal tubules leading to decreased excretion of waste products, resulting in elevated BUN and creatinine levels. The normal BUN/creatinine ratio suggests that the impairment is due to renal tubular dysfunction rather than prerenal causes like hypovolemia or postrenal causes like urinary obstruction. Increased nitrogen intake would not produce this specific pattern of results. Fluid resuscitation would likely result in dilution of BUN and creatinine levels, leading to lower values.

Correct Answer: C

Rationale: The correct answer is C: Measure the patient�s urinary output every hour. This is crucial because monitoring urinary output is essential in assessing the patient�s renal function and the effectiveness of the intra-aortic balloon pump in improving cardiac output. Hourly measurement helps in early detection of any changes that may indicate complications. A: Positioning the patient supine at all times is not necessary and can lead to complications. B: Avoiding the use of anticoagulant medications is not appropriate as they are often necessary to prevent clot formation around the balloon pump. D: Providing a massive range of motion for all extremities is not recommended for a patient with an intra-aortic balloon pump as it can dislodge the device or cause harm.

Correct Answer: D

Rationale: The correct answer is D, Metoprolol tartrate (Lopressor). Metoprolol is a cardioselective beta-blocker that primarily targets beta-1 receptors in the heart, making it less likely to exacerbate asthma compared to non-selective beta-blockers like Propranolol (choice B) and Pindolol (choice C). Carteolol (choice A) is also a non-selective beta-blocker and can potentially worsen asthma symptoms. Metoprolol's selectivity for beta-1 receptors minimizes bronchoconstriction, making it the safest choice for a client with asthma and high blood pressure.

Correct Answer: C

Rationale: The correct response is C: Your pain medication is already at the highest possible dose. This response acknowledges the patient's pain and reassures them that they are already receiving the maximum safe amount of pain medication. By stating this, the nurse is validating the patient's experience and showing empathy. It is important for the nurse to communicate clearly about the medication to manage the patient's expectations. Choice A is incorrect as it dismisses the patient's pain and can come across as insensitive. Choice B may be well-intentioned but does not address the immediate concern of the patient's pain. Choice D is irrelevant to the patient's statement about pain and does not offer any immediate support or reassurance regarding the pain management.

Correct Answer: A

Rationale: The correct answer is A because assessing the patient and family's developmental stages and needs is crucial in understanding their current situation and determining the appropriate care plan. By assessing developmental stages, the nurse can tailor interventions to meet the family's specific needs. This assessment also helps in identifying potential challenges or areas requiring support. Choice B is incorrect as it focuses solely on the physical environment and does not address the family's developmental stages and needs. Choice C is incorrect as it emphasizes identifying family members without considering the importance of understanding their developmental stages and needs in providing family-centered care. Choice D is incorrect as it concentrates on family dynamics without directly addressing the crucial aspect of assessing developmental stages and needs for effective family-centered care.
