Correct Answer: C

Rationale: Irritability in infants can indicate worsening dehydration, which needs to be reported. Weight gain (Choice A) would be a positive finding, indicating adequate fluid intake. Poor appetite (Choice B) is common with diarrhea but not as concerning as irritability. Decreased urination (Choice D) can also be a sign of dehydration, but irritability is more specific to worsening dehydration in this case.

Correct Answer: D

Rationale: The correct answer is to pour warm water over the client's perineum. This intervention can help stimulate voiding after catheter removal by promoting relaxation of the perineal muscles and increasing sensory input to the bladder. Assessing for bladder distention after 6 hours (Choice A) is important but not the initial intervention for difficulty voiding. Encouraging the client to use a bedpan in the supine position (Choice B) may not be effective in promoting voiding. Restricting the client's intake of oral fluids (Choice C) is not appropriate as hydration is important for urinary function.

Correct Answer: A

Rationale: The correct instruction the nurse should include is to advise the client to avoid crowded places. Immunocompromised clients undergoing chemotherapy are at a higher risk of infections, so avoiding crowded places can help reduce exposure to pathogens. Wearing a mask at home is not necessary unless someone in the household is sick. Drinking unfiltered water can introduce harmful bacteria, increasing the risk of infection. Avoiding washing hands frequently is incorrect as hand hygiene is crucial in preventing the spread of infections.

Correct Answer: C

Rationale: Instructing the client to avoid the Valsalva maneuver is crucial after rhinoplasty to reduce strain and the risk of bleeding. Administering humidified oxygen may not be directly related to postoperative care for rhinoplasty. Restricting fluids is not typically necessary unless specifically indicated by the healthcare provider. Applying heat packs to the nose is contraindicated after rhinoplasty as it can increase the risk of bleeding and should be avoided.

Correct Answer: A

Rationale: The correct answer is A: Monitor gastric residual volume and check for abdominal distension. These assessments are critical to evaluate the patient's tolerance to enteral feeding. Monitoring gastric residual volume helps determine gastric emptying, while checking for abdominal distension can identify complications like bowel obstruction. Choices B, C, and D are important aspects of enteral feeding care but are not the primary assessments. Ensuring the correct placement of the feeding tube is crucial for safety, assessing for signs of dehydration and electrolyte imbalances is essential for overall patient well-being, and elevating the head of the bed is vital to prevent aspiration. However, these are not the key assessments specifically related to enteral feeding.
