Correct Answer: B

Rationale: The correct answer is B because verifying tube placement before feeding is essential to prevent pulmonary aspiration. If the tube is not correctly positioned in the stomach, there is a risk of feeding going into the lungs. Observing the color of gastric contents (A) may not always indicate correct placement. Adding blue food coloring (C) is unnecessary and could cause confusion. Running the formula over 12 hours (D) does not address the risk of pulmonary aspiration and does not ensure proper tube placement.

Correct Answer: B

Rationale: The correct answer is B because giving a hypertonic solution enema to a patient with fluid volume excess can worsen the condition by drawing more fluid into the colon. This can lead to further fluid volume overload and electrolyte imbalances. The other choices are incorrect because: A: Normal saline enema is appropriate for constipation. C: Kayexalate enema is used to treat hyperkalemia, not hypokalemia. D: Oil retention enema is indicated for constipation to soften stool.

Correct Answer: C

Rationale: Rationale: Choice C is correct because understanding the illness from the patient's perspective helps nurses provide individualized care. By empathizing with the patient's experience, nurses can tailor support to meet their specific needs. Describing personal experiences (A) may not be appropriate as it shifts the focus from the patient. Encouraging fighting for a cure (B) may not align with the patient's wishes for quality of life. Assisting with life review (D) can be beneficial but may not be a priority for all patients. Providing interventions for end-of-life closure (E) is important, but understanding the illness from the patient's perspective (C) forms the foundation for effective support.

Correct Answer: A

Rationale: The correct answer is A: Liver function tests (LFTs). Yellow skin can indicate jaundice, a sign of liver dysfunction, often seen in patients with liver issues or chemotherapy-related liver toxicity. LFTs including bilirubin, ALT, AST, and ALP can help assess liver function. B: Complete blood count (CBC) and C: Platelet count are not directly related to yellow skin and would not provide information on liver function. D: Blood urea nitrogen and creatinine are tests for kidney function, not liver function. While kidney dysfunction can sometimes cause yellow skin, LFTs are more specific for assessing liver function in this context.

Correct Answer: B

Rationale: The correct answer is B: Denial of imminent death on the part of the family or the patient. This is a common cause of patient care dilemmas at the end of life because denial can lead to unrealistic expectations, difficulty in making important decisions, and inadequate planning for end-of-life care. This can result in unnecessary suffering for the patient and added stress for the family. Incorrect choices: A: Poor communication between the family and the care team can contribute to challenges in providing appropriate care but may not be the primary cause of patient care dilemmas at the end of life. C: Limited visitation opportunities for friends and family, while important for psychosocial support, may not directly cause patient care dilemmas. D: Conflict between family members can complicate decision-making processes, but it is not necessarily a primary cause of patient care dilemmas at the end of life.
