Correct Answer: D

Rationale: Checking the client's blood pressure and pulse deficit is essential before mobilizing a client out of bed, especially after surgery. This assessment helps ensure the client's stability and readiness for mobilization. Administering oxygen or pivoting the client without prior assessment could pose risks if the client is not medically stable. Helping the client lie back down without proper evaluation may delay necessary interventions if the client is indeed ready for mobilization.

Correct Answer: A

Rationale: The correct answer is to assess the oral cavity. 'Edentulous' means without teeth, so the nurse should assess the oral cavity for any issues related to oral health, dentures, or potential complications. This assessment is crucial to prevent oral health problems and ensure proper care for the patient. Assessing the room for drafts (choice B) is unrelated to the patient's edentulous status and does not address the immediate care needs. Assessing ankles for edema (choice C) is important for circulatory assessment but not directly related to the patient being edentulous. Assessing for reduced sensations (choice D) would be more relevant for neurological or sensory concerns, which are not specifically associated with being edentulous.

Correct Answer: A

Rationale: Discharge planning for a patient admitted to the neurological unit with a stroke diagnosis should begin at the time of admission. Initiating discharge planning early allows for a comprehensive assessment of the patient's needs, enables better coordination of care, and ensures a smooth transition from the hospital to the next level of care. Option B is incorrect because waiting until the day before discharge does not provide enough time for adequate planning. Option C is incorrect because waiting until outpatient therapy is no longer needed delays the planning process. Option D is incorrect because waiting until the discharge destination is known may result in rushed planning and inadequate preparation for the patient's needs.

Correct Answer: A

Rationale: Postural hypotension is a common sign of extracellular fluid volume deficit due to decreased blood volume, leading to a drop in blood pressure upon standing. Distended neck veins, dependent edema, and bradycardia are not typically associated with extracellular fluid volume deficit. Distended neck veins are more indicative of fluid volume overload, dependent edema is a sign of fluid retention, and bradycardia is not a common finding in extracellular fluid volume deficit.

Correct Answer: C

Rationale: The correct dosage calculation is to divide the prescribed dose by the concentration of the medication to determine the volume needed. In this case, 3 mg (prescribed dose) divided by 4 mg/mL (concentration) equals 0.75 mL. Therefore, the healthcare provider should administer 0.75 mL of hydromorphone to the client. Choices A, B, and D are incorrect because they do not accurately calculate the required volume based on the prescription and concentration provided.
