Correct Answer: A

Rationale: The nurse should offer support without pressuring the client. Stating, "I am available to talk if you should change your mind," acknowledges the client's decision while leaving the door open for future discussions. Choice B is incorrect as it assumes the client's decision is final without offering further support. Choice C directs the client back to the provider without addressing the nurse's availability. Choice D commits to a future discussion without considering the client's current preference.

Correct Answer: A

Rationale: The correct answer is A because using the spirometer every hour while awake is an effective way to prevent respiratory complications. This frequency helps in maintaining lung function and preventing atelectasis. Choice B is incorrect because blowing too hard into the spirometer can lead to hyperventilation and dizziness, making choice C also incorrect. Choice D is wrong as waiting to use the spirometer only when feeling short of breath may not provide optimal lung expansion and can lead to respiratory issues.

Correct Answer: B

Rationale: Increased urine output is the correct assessment finding that indicates the client is responding to treatment for dehydration. When a client is dehydrated, their urine output tends to decrease as the body tries to conserve fluids. Therefore, an increase in urine output suggests that the client's hydration status is improving. Dry mucous membranes (Choice A) are a sign of dehydration and would not indicate a positive response to treatment. Decreased heart rate (Choice C) and elevated blood pressure (Choice D) are not specific indicators of hydration status in a client with dehydration.

Correct Answer: B

Rationale: Enoxaparin should be administered with the needle at a 90-degree angle to ensure proper subcutaneous delivery. Choice B is correct as it aligns with the recommended angle for subcutaneous injections. Administering enoxaparin at a 45-degree angle (Choice A), 30-degree angle (Choice C), or 15-degree angle (Choice D) would not be appropriate and may lead to improper administration or absorption of the medication.

Correct Answer: A

Rationale: An oil retention enema containing mineral oil is the most suitable choice to help soften and loosen a fecal impaction before digital removal. Mineral oil lubricates and softens the stool, facilitating passage. Saline enemas draw water into the colon to promote bowel movements but may not effectively soften a fecal impaction. Soapy water enemas are primarily for cleansing, not softening stool. Hypertonic enemas eliminate fluid from the body and are not appropriate for loosening fecal impactions.
