Correct Answer: B

Rationale: The correct answer is B because informing the child that they will feel discomfort during catheter insertion is crucial to prepare them for the procedure. Choice A is incorrect as children should not handle medical supplies. Choice C is inappropriate as using a restraint can cause anxiety and fear in the child. Choice D is not necessary as having parents present can provide comfort and support to the child during the procedure.

Correct Answer: B

Rationale: The correct answer is B: Amylase. Amylase is typically elevated in clients with acute pancreatitis due to inflammation of the pancreas. Elevated serum creatinine levels are more indicative of kidney dysfunction rather than pancreatitis. Hemoglobin levels are not directly related to pancreatitis. While blood glucose levels can be affected by pancreatitis, they are not typically the primary laboratory result expected to be elevated in this condition.

Correct Answer: D

Rationale: The correct answer is D: Cured meats. Cured meats contain tyramine, which can lead to a hypertensive crisis in clients taking tranylcypromine. Bananas, milk, and yogurt do not contain significant amounts of tyramine and are safe for clients taking this medication. Therefore, the nurse should instruct the client to avoid cured meats to prevent adverse effects.

Correct Answer: C

Rationale: The correct answer is C. Chest tube drainage of more than 100 mL/hr may indicate active bleeding, which is a serious complication post-thoracotomy surgery. This finding should be reported to the healthcare provider immediately for further evaluation and intervention. Choices A, B, and D are within normal limits for a client 2 hours post-thoracotomy and do not require immediate reporting. Oxygen saturation of 95% is acceptable, and a heart rate of 88/min is within the normal range for an adult.

Correct Answer: C

Rationale: The correct measure to include when caring for a client on contact precautions is to wear gloves when providing care. Gloves help prevent the spread of infection and cross-contamination. Choice A is incorrect because the protective gown should be removed before leaving the client's room to prevent the spread of pathogens. Choice B is incorrect as clients on contact precautions should be in a room with negative pressure to prevent the spread of airborne contaminants. Choice D is incorrect as wearing a mask when changing linens is not specifically required for contact precautions.
