Correct Answer: D

Rationale: The correct answer is D, Parenteral albumin (Albuminar). Parenteral albumin is not typically indicated for dehydration resulting from diarrhea. In this case, fluid replacement therapy with intravenous fluids such as parenteral half normal saline would be more appropriate. Oral psyllium and oral potassium supplement are not the primary interventions for managing dehydration due to watery diarrhea. Oral psyllium is a fiber supplement used for constipation rather than diarrhea. Oral potassium supplements may be necessary if potassium levels are low due to dehydration, but the priority is fluid replacement. Therefore, choices A and B are less relevant in this scenario.

Correct Answer: C

Rationale: The correct answer is C: 'Do not discontinue the medication abruptly.' It is crucial for clients prescribed prednisone to not stop the medication suddenly to prevent adrenal insufficiency, as this medication suppresses the body's natural production of cortisol. Choice A is incorrect because prednisone should be taken with food to minimize gastrointestinal side effects, not necessarily to prevent stomach upset. Choice B is incorrect as there is no specific need to avoid sunlight while taking prednisone. Choice D is not directly related to prednisone use; while adequate fluid intake is generally beneficial, it is not a specific instruction for prednisone administration.

Correct Answer: B

Rationale: Enoxaparin is a medication that is administered subcutaneously, which means it should be injected into the fatty tissue layer beneath the skin. Administering enoxaparin at a 90-degree angle ensures proper absorption and reduces the risk of injecting the medication into muscle tissue, which could affect its effectiveness. Injecting the medication at a 45-degree angle may lead to improper absorption as it may not reach the subcutaneous tissue adequately. Injecting the medication into the muscle instead of subcutaneously can alter the absorption rate and therapeutic effects. Pinching the skin before injecting is not necessary for administering enoxaparin subcutaneously and may cause unnecessary discomfort to the client.

Correct Answer: D

Rationale: The correct answer is D. A potassium level of 5.4 mEq/L is above the expected reference range, indicating hyperkalemia. Hyperkalemia can lead to serious complications such as dysrhythmias, making it important for the healthcare professional to report this finding to the provider for further evaluation and intervention. Choices A, B, and C fall within normal ranges and do not pose an immediate risk to the client's health, so they would not warrant immediate reporting to the provider. Elevated BUN or creatinine levels may indicate kidney dysfunction, while a sodium level of 143 mEq/L falls within the normal range for adults and does not typically require urgent intervention.

Correct Answer: B

Rationale: Offering a wet washcloth for the client to wash their face is a soothing and calming activity that can help the client relax before bedtime, promoting better sleep. Providing a late supper can lead to indigestion and disrupt sleep. Performing range of motion exercises may increase alertness rather than promoting relaxation. Preparing a hot cocoa or tea containing caffeine close to bedtime can interfere with falling asleep.
