Critical Care Nursing Questions and Answers PDF

Correct Answer: D

Rationale: The correct answer is D because the presence of red blood cells and albumin in the urine indicates possible kidney damage from the blunt trauma. This is concerning as it may suggest renal injury or dysfunction. A: Creatinine levels in the urine being similar to blood levels is normal as creatinine is filtered by the kidneys. B: Sodium and chloride being present in the urine is expected as they are components of urine. C: Urine uric acid levels matching serum levels is common as uric acid is excreted by the kidneys. In summary, the presence of red blood cells and albumin in the urine is abnormal and indicates potential kidney damage, making it the correct answer.

Correct Answer: C

Rationale: The correct answer is C because maintaining eye contact with the patient during explanations is a non-verbal way to show attentiveness and empathy, which can help reduce the patient's anxiety. This behavior demonstrates active listening and engagement, making the patient feel heard and understood. A: Staying in the patient's room to complete documentation is not an effective use of presence as it does not involve direct interaction with the patient. B: Having a conversation in the patient's room that excludes the patient is also not an effective use of presence as it does not involve engaging with the patient. D: Focusing on specific nursing care tasks while in the patient's room, although important, may not necessarily demonstrate presence in reducing the patient's anxiety.

Correct Answer: A

Rationale: The correct answer is A: Alveoli collapse and atelectasis occurs. When fluid is present in the alveoli, it impairs the surface tension necessary for the alveoli to remain open, leading to collapse and atelectasis. This prevents proper gas exchange, resulting in hypoxemia. Choice B is incorrect because impaired gas diffusion typically occurs with conditions affecting the alveolar-capillary membrane, not fluid in the alveoli. Choice C is incorrect as hypoventilation refers to decreased ventilation, not specifically related to fluid in the alveoli. Choice D is incorrect as fluid in the alveoli is not a direct indicator of heart failure.

Correct Answer: B

Rationale: The correct answer is B because it shows understanding that the PAC helps in managing fluid therapy effectively. The PAC measures pressures in the heart and lungs, guiding fluid management. Choice A is incorrect as the PAC is not primarily for IV fluid administration. Choice C shows understanding of the catheter placement but not its purpose. Choice D is incorrect as the PAC is not for the heart to heal but to monitor cardiac status.

Correct Answer: A

Rationale: The correct answer is A: Obtain the permission of the custodial parent for the surgery. In this scenario, the client is a minor (16 years old), which means they are not legally able to provide informed consent for medical procedures. The custodial parent holds legal responsibility for the minor's healthcare decisions. Thus, obtaining the permission of the custodial parent is crucial to ensure valid informed consent. Choice B is incorrect because the non-custodial parent's consent may not be legally required if the custodial parent is available to provide consent. Choice C is incorrect because obtaining consent should precede any administration of medications. Choice D is incorrect as the stepfather's consent may not hold legal weight unless designated as a legal guardian.
