Correct Answer: C

Rationale: The nurse should instruct the client to liberally apply prescribed lotion to the treatment area. Prescribed hydrating lotions help soothe and protect irradiated skin, reducing dryness, redness, and scaling. Sitting in the sun can further damage the skin. Applying moist heat may exacerbate the skin condition. Washing the area with antimicrobial soap can be too harsh and further irritate the skin.

Correct Answer: A

Rationale: In heart failure, the accumulation of fluid can lead to peripheral edema, which is swelling in the extremities. This is a common sign that healthcare professionals should monitor for. While tachycardia (increased heart rate), bradycardia (decreased heart rate), and hypotension (low blood pressure) can also occur in heart failure, they are not the primary signs typically associated with this condition. Therefore, peripheral edema is the most relevant sign to monitor in this case.

Correct Answer: D

Rationale: Correct! All of these factors should be considered when assessing a client for potential drug interactions. The client's diet can interact with certain medications, the client's age can affect metabolism and drug sensitivity, and genetic background can impact how the body processes medications. Therefore, it is essential for the nurse to take into account all these factors to ensure safe and effective drug therapy. Choices A, B, and C are incorrect because each of these factors alone can contribute to potential drug interactions, making it crucial to consider all of them together.

Correct Answer: B

Rationale: The client's Glasgow Coma Score is 7. This is calculated by assigning 2 points for eye-opening to pain, 2 points for incomprehensible sounds, and 3 points for flexion posturing. Choices A, C, and D are incorrect. Choice A (4) would be the score if the client displayed decerebrate posturing instead of flexion posturing. Choice C (9) would be the score if the client exhibited eye-opening to speech, confused speech, and decorticate posturing. Choice D (10) would be the score if the client showed eye-opening spontaneously, oriented speech, and obeyed commands, which is not the case here.

Correct Answer: B

Rationale: The correct action when administering potassium chloride is to dilute the medication before administration. Potassium chloride is a highly concentrated solution that can cause irritation and potential complications if not properly diluted. Administering it rapidly (choice A) can lead to adverse effects. Giving it as a bolus (choice C) or administering it intramuscularly (choice D) are inappropriate routes for potassium chloride administration and can result in harm to the patient.
