The healthcare professional seeks to assess the renal function of an elderly client who is about to receive a nephrotoxic medication. Which of the following labs provides the best indicator for renal function?

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.

Correct Answer: A

Rationale: The nurse's actions of providing an analgesic medication and darkening the room aim to decrease stimuli from the cerebral cortex. Reduction of environmental stimuli, especially light and noise, from the cerebral cortex, which is an area of arousal, facilitates sleep. By decreasing input to this area, the client is more likely to fall asleep and stay asleep. Choices B, C, and D are incorrect because the scenario does not involve stimulating hormonal changes, influencing the circadian rhythm, or alerting the hypothalamus.

Correct Answer: C

Rationale: The correct answer is to prevent accumulation of fluids and gas. Immediately after abdominal surgery, the NG tube is used to keep the stomach decompressed, preventing the accumulation of fluids and gas. This helps in maintaining decompression to prevent surgical-site disruption and fluid loss through vomiting. Choices A, B, and D are incorrect because the primary purpose of the NG tube following abdominal surgery is to prevent complications related to fluid and gas build-up rather than simplifying medication administration, measuring input and output, or collecting specimens.

Correct Answer: B

Rationale: In this scenario, the priority is the safety and well-being of the client. The neighborhood facility's lack of experience in caring for a client with an epidural catheter for continuous opioid infusion raises concerns about the quality of care they can provide. Therefore, the most appropriate action for the discharge planning nurse is to explain the situation to the client and family and seek another long-term care facility that can provide the necessary care. Option A, arranging for immediate in-services, may not be feasible or timely, considering the urgent need for appropriate care. Option C, encouraging the family to hire private duty nurses, does not ensure the facility's overall capability to manage the client's complex needs. Option D, 'None of the above,' is not the best choice as the client's safety should be the priority in this situation.

Correct Answer: A

Rationale: The correct answer is Good Samaritan laws. These laws protect individuals who provide voluntary emergency care from being held liable for any unintended injury or harm that may occur during the care. Good Samaritan laws encourage individuals to assist in emergencies without fear of legal repercussions. HIPAA, on the other hand, focuses on safeguarding patient information and privacy, ensuring confidentiality. The Patient Self-Determination Act (PSDA) pertains to a patient's rights to make decisions about their medical treatment and advance directives. OBRA, enacted in the late 1980s, aims to improve the quality of care in nursing homes and enhance residents' quality of life, focusing on nursing home reform and standards, which is not directly related to immunity for emergency care providers.

Correct Answer: A

Rationale: When caring for a client on ventilator support pending organ donation, maintaining the systolic blood pressure at 70mmHg or greater is crucial to ensure a proper blood supply to the donor organ. This goal is a priority to maintain the viability of the organ for donation. Choices B, C, and D are incorrect because they are unnecessary and not directly related to the immediate goal of organ donation. Maintaining urinary output, body temperature, or hematocrit levels are not the primary concerns in this situation.

Correct Answer: C

Rationale: Toradol is the correct answer because it is an NSAID known for its effectiveness in managing acute pain for short durations. It can be administered via intramuscular (IM), intravenous (IV), or oral (PO) routes. Advil (choice A) and Aleve (choice B) are commonly used for mild to moderate pain but may not be as effective for acute pain requiring immediate relief. Bextra (choice D) was withdrawn from the market due to safety concerns, making it an inappropriate choice for acute pain management.

Correct Answer: D

Rationale: All of the provided choices are antiviral drug classes used in the treatment of HIV/AIDS. Nucleoside reverse transcriptase inhibitors, such as tenofovir and emtricitabine, work by interfering with the virus's ability to replicate. Protease inhibitors, like atazanavir and darunavir, block an enzyme that HIV needs to make copies of itself. HIV fusion inhibitors, for instance, enfuvirtide, prevent HIV from entering human cells. Therefore, 'all of the above' is the correct answer as all the listed drug classes are commonly used in managing HIV infections. Choices A, B, and C are all essential components of antiretroviral therapy for HIV, targeting different stages of the virus's life cycle. The combination of drugs from these classes is often recommended to effectively control HIV replication and reduce viral load.

Correct Answer: C

Rationale: All nurses should be concerned with preventing the transmission of microorganisms to themselves and others. A primary way to achieve this is through asepsis. Nursing practice emphasizes providing a safe environment to shield clients, family, and healthcare providers from infections. Choices A, B, and D are incorrect. While drug-resistant bacteria, critical microorganisms, and overprescription of bacteriostatic drugs are important, nurses' primary focus should be on preventing microorganism transmission to ensure safety and well-being.
