Correct Answer: B

Rationale: An individual may receive medical care without giving informed consent in an emergency, life-or-death situation. This exception allows healthcare providers to provide immediate treatment to save a person's life or prevent serious harm when time is of the essence. Choices A, C, and D are incorrect because in all other situations, informed consent is required. The durable power of attorney for health care should be involved if available, the physician should have a discussion with the client in non-life-threatening situations, and in cases where clients are unable to speak for themselves, their designated representative or responsible party should be involved in the consent process.

Correct Answer: B

Rationale: The correct answer is 'the severity of the client's condition and the priority decision.' When determining the method of splinting, it is crucial to consider the severity of the client's condition and make decisions based on their priority. Choice A is incorrect because while the location of the injury and whether it is open or closed are important factors, they do not always dictate the method of splinting. Choice C is incorrect as the number of available rescuers and the type of splints may impact the execution of splinting but do not solely dictate the method. Choice D is incorrect as it suggests that all the factors mentioned dictate the method, but in reality, the severity of the client's condition and the priority decision are the primary factors.

Correct Answer: C

Rationale: The correct statement for a client with GERD is, 'I should sit up after eating.' This helps prevent reflux by keeping the stomach contents down. Choice A is incorrect as eating right before bedtime can exacerbate GERD symptoms by increasing the likelihood of reflux during the night. Choice B is incorrect because consuming large meals can lead to increased stomach pressure and worsen reflux symptoms. Choice D is incorrect because lying flat after eating can promote reflux due to gravity assisting the flow of stomach contents into the esophagus, worsening GERD.

Correct Answer: A

Rationale: The most appropriate action in this scenario is to call the surgeon and ask them to see the client to clarify the information. It is the responsibility of the physician to explain and clarify the procedure to the client, ensuring informed consent. Answer B is incorrect as nurses should not provide detailed medical explanations beyond their scope of practice. Answer C is incorrect as the physician's notes may not capture the client's current understanding accurately. Answer D is incorrect because the client's own understanding, not the family's, is crucial for informed decision-making regarding the surgery.

Correct Answer: D

Rationale: In the context of an elderly client, assessing renal function before administering a nephrotoxic medication is crucial. While urinalysis and blood urea nitrogen provide valuable information on hydration status and overall health clues, they are not specific indicators of renal function. The chemistry of electrolytes may show abnormalities in renal failure, but it does not directly measure the kidneys' ability to eliminate waste. Creatinine clearance, on the other hand, is considered the best indicator for renal function in the elderly. This test accounts for decreases in lean body mass that can affect blood creatinine levels and is widely used to estimate the glomerular filtration rate, reflecting the kidneys' filtration capability. Therefore, creatinine clearance is the most appropriate lab test to assess renal function in this scenario.
