Correct Answer: C

Rationale: The correct answer is C: Sedation. Chlorpromazine, an antipsychotic medication, commonly causes sedation as an adverse effect. Weight gain (choice A) is a potential side effect of some antipsychotic medications, but it is not specifically associated with chlorpromazine. Dry mouth (choice B) is a common anticholinergic side effect of many medications but is not a prominent adverse effect of chlorpromazine. Diarrhea (choice D) is not a typical adverse effect of chlorpromazine.

Correct Answer: C

Rationale: Jugular vein distention is a classic sign of left-sided heart failure due to fluid overload in the pulmonary circulation. This occurs because the heart's left side is unable to pump effectively, causing increased pressure in the pulmonary veins and leading to blood backing up into the pulmonary circulation. Peripheral edema (choice A) and dependent edema (choice D) are more commonly associated with right-sided heart failure where blood pools in the systemic circulation, causing swelling in the extremities. Bradycardia (choice B) is not typically a direct consequence of left-sided heart failure; instead, tachycardia is more commonly seen as the heart compensates for its reduced efficiency.

Correct Answer: A

Rationale: The correct answer is A. A gastric residual of 200 mL or more indicates delayed gastric emptying, which can be a sign of potential complications such as aspiration or intolerance to the enteral feedings. This finding should be reported to the healthcare provider for further evaluation and possible intervention. Choices B, C, and D are within normal limits and do not require immediate reporting. A pH of 5.0 is normal for gastric contents, bowel sounds in all quadrants indicate normal gastrointestinal motility, and a temperature of 37.5°C (99.5°F) is within the normal range.

Correct Answer: C

Rationale: A temperature of 37.8°C (100°F) should be reported to the provider as it can indicate infection, a common postoperative complication. A normal heart rate of 80/min (Choice A), white blood cell count of 9,000/mm3 (Choice B), and blood pressure of 118/78 mm Hg (Choice D) are within normal ranges and do not necessarily indicate a complication postoperatively.

Correct Answer: B

Rationale: The vastus lateralis is the preferred site for intramuscular injections in adults due to its large muscle mass and low risk of complications. The deltoid, although a common site for vaccines, has a smaller muscle mass and may not be suitable for all types of medications. The rectus femoris is a muscle in the thigh that is more commonly used for intramuscular injections in infants. The dorsogluteal site is no longer recommended due to its proximity to major nerves and blood vessels.
