Correct Answer: B

Rationale: The correct answer is to assist the client to the left Sims' position when administering an enema. This position helps facilitate the flow of the enema solution into the rectum. Placing the client in a high-Fowler's position (Choice A) is not ideal for administering an enema. Inserting the enema tubing 2.5 cm (1 in) into the rectum (Choice C) is incorrect as it should be inserted 7.5-10 cm (3-4 in) for an adult. Lubricating the tip of the enema tubing with petroleum jelly (Choice D) is a correct step to ease insertion but is not the most critical action among the choices provided.

Correct Answer: D

Rationale: A client with bipolar disorder and impaired social interactions should be placed closest to the nurse's station for closer monitoring. Clients with bipolar disorder may experience mood swings, including manic episodes that can lead to impulsive behaviors or aggression. Placing such a client near the nurse's station allows for quick intervention and monitoring of their social interactions, especially if they are impaired. The other options, such as anxiety disorder, somatic symptom disorder, and depressive disorder, do not inherently require immediate proximity to the nurse's station based on the information provided.

Correct Answer: A

Rationale: The correct answer is A: Potassium 3.5 mEq/L. Digoxin can cause hypokalemia as an adverse effect. Monitoring potassium levels is crucial because low potassium levels can increase the risk of digoxin toxicity. Choices B, C, and D are incorrect as they are not directly associated with potential adverse effects of digoxin. Sodium levels are not typically affected by digoxin, calcium levels are not a primary concern with digoxin therapy, and magnesium levels are not the most important to monitor for digoxin adverse effects.

Correct Answer: C

Rationale: The correct answer is C. Pain in the right shoulder after a cholecystectomy is common due to residual gas from the procedure. Choices A, B, and D are incorrect. It is important to avoid heavy lifting for a longer period than just 1 week to prevent complications. Resuming usual activities after 2 weeks may not be appropriate depending on the individual's recovery. Following a low-protein diet is not a standard recommendation post-cholecystectomy.

Correct Answer: C

Rationale: In Cushing's disease, there is increased cortisol production, which can lead to various metabolic disturbances. One of the common findings is an increased serum potassium level. The other options are incorrect because Cushing's disease typically causes hyperglycemia, not decreased serum glucose levels (A), lymphocytopenia, not increased lymphocyte count (B), and hyponatremia, not decreased serum sodium level (D).
