Correct Answer: C

Rationale: The correct answer is C. Clients with hypertension should avoid salt substitutes because they often contain potassium, which can raise potassium levels. Choice A is incorrect as decreasing potassium intake is not necessary unless advised by a healthcare provider. Choice B is incorrect as not all clients with hypertension need to take medication for life. Choice D is incorrect as grapefruit juice does not significantly impact hypertension management.

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: B

Rationale: A positive antinuclear antibody (ANA) titer is a significant finding in clients with systemic lupus erythematosus (SLE) as it indicates active disease. This result should be reported to the provider for further evaluation and management. Choices A, C, and D are within normal ranges and not specifically indicative of disease activity in SLE. Therefore, they do not require immediate reporting to the provider.

Correct Answer: C

Rationale: Using an abduction pillow between the client's legs is essential in maintaining proper alignment and preventing dislocation of the hip joint following a hip arthroplasty. Encouraging the client to lie flat in bed (Choice A) is not recommended as early mobilization is crucial for preventing complications. Applying heat to the incision site (Choice B) is not typically done immediately postoperatively. Placing a trochanter roll under the client's knees (Choice D) is not as beneficial as using an abduction pillow to maintain proper positioning.

Correct Answer: D

Rationale: Verifying the client's tube placement is the priority before administering any enteral feeding. This step ensures that the tube is correctly positioned in the stomach or intestines, minimizing the risk of complications such as aspiration. Checking the residual volume, elevating the head of the bed, and flushing the tube are important steps but should occur after confirming the tube placement to ensure the feeding is delivered safely and effectively.
