Correct Answer: B

Rationale: After a total hip arthroplasty, it is crucial to prevent hip dislocation. Placing an abduction pillow between the client's legs helps maintain proper alignment of the hip joint and prevents adduction, which could lead to dislocation. Therefore, choice B is the correct action. Choice A is incorrect because positioning the client supine with a pillow between the legs does not provide the necessary abduction to prevent dislocation. Choice C, placing a pillow under the client's knees, does not address the need for abduction. Choice D, positioning the client's legs in adduction, is incorrect as adduction increases the risk of hip dislocation following hip arthroplasty.

Correct Answer: B

Rationale: During the first trimester, it is recommended to increase caloric intake by 300 calories per day to support fetal growth and development. Choice A suggesting an increase of 600 calories is excessive and unnecessary. Choice C advising to maintain prepregnancy caloric intake could lead to inadequate nutrition for the developing fetus. Choice D recommending an increase of 150 calories is insufficient to meet the increased energy demands of pregnancy.

Correct Answer: C

Rationale: Encouraging the client to take frequent rest periods is an appropriate intervention for managing mania in a client with bipolar disorder. During a manic episode, individuals often have increased energy levels, decreased need for sleep, and may engage in high-risk behaviors. Encouraging regular rest periods can help reduce stimulation and promote relaxation, which may assist in stabilizing mood. Choices A and B are not as effective in managing manic symptoms, as they do not directly address the client's need for rest and relaxation. Choice D is inappropriate because placing the client in seclusion can increase feelings of anxiety and agitation, worsening the manic episode.

Correct Answer: A

Rationale: The correct answer is A. Administering antibiotics late must be reported as it can compromise the effectiveness of the treatment. This delay can lead to subtherapeutic levels of the antibiotic in the client's system, potentially reducing its efficacy in combating the infection. Choice B, a client vomiting shortly after taking medication, should be noted but does not necessarily require an incident report unless it is a frequent occurrence. It could indicate a possible adverse reaction or intolerance to the medication. Choice C, a client requesting a statin at a specific time, and choice D, a client asking for pain medication slightly earlier, do not involve medication errors or deviations that pose immediate risks to the client's health, so they do not require incident reports.

Correct Answer: C

Rationale: Enuresis is a common symptom of urinary tract infections in school-age children. It is often a presenting symptom due to irritation of the bladder. Periorbital edema (Choice A) is more indicative of conditions like nephrotic syndrome or renal disorders. Decreased frequency of urination (Choice B) is not typically associated with urinary tract infections. Diarrhea (Choice D) is not a common symptom of urinary tract infections but may occur due to other reasons like gastrointestinal infections.
