Correct Answer: D

Rationale: In caring for a client with severe depression, safety is a critical priority. The nurse must address precautions to prevent suicide as part of the care plan. While nutrition, elimination, and activity are important aspects of care, safety takes precedence due to the immediate risk of harm associated with depression. Ensuring the client's safety by implementing measures to prevent self-harm or suicide is the priority intervention. Addressing nutrition, elimination, and activity can follow once the client's safety is assured.

Correct Answer: C

Rationale: A systolic blood pressure of 145 mm Hg falls within the range of 140-159 mm Hg, which is classified as Stage I hypertension. Normotensive individuals have a systolic blood pressure less than 120 mm Hg, making choice A incorrect. Prehypertension is characterized by a systolic blood pressure ranging from 120-139 mm Hg, excluding choice B. Stage II hypertension is diagnosed when the systolic blood pressure is greater than 160 mm Hg, making choice D incorrect.
Therefore, the correct classification for a systolic blood pressure of 145 mm Hg is Stage I hypertension.

Correct Answer: B

Rationale: After surgical intervention for imperforate anus, the infant should be placed in a side-lying position with the legs flexed. This position helps reduce edema and pressure on the surgical site, preventing strain and promoting comfort. Placing the infant supine with no head elevation (
Choice
A) doesn't offer adequate support and may increase pressure on the area. Side-lying with the legs extended (
Choice
C) doesn't help reduce edema and pressure effectively. Placing the infant supine with the head elevated 30 degrees (
Choice
D) isn't recommended as it may not provide adequate support and comfort needed for recovery.

Rationale: The correct answer is 'hair loss.' Alopecia is a medical term that specifically refers to the condition of hair loss, usually in patches or all over the body.
Choice A, 'body lice,' refers to a parasitic infestation and is not related to alopecia.
Choice B, 'lack of ear lobes,' is completely unrelated to the term alopecia, which is solely about hair loss.
Choice C, 'Indigestion,' has no connection to alopecia as it pertains to digestive issues, not hair loss.
Therefore, the correct description for a patient diagnosed with alopecia is 'hair loss.'

Correct Answer: D

Rationale: Intussusception is a condition in which a proximal segment of the bowel telescopes or prolapses into a distal segment of the bowel. This leads to bowel obstruction and potential ischemia. It is not an acute bowel obstruction, as the obstruction is caused by the telescoping of bowel segments rather than a blockage in the bowel lumen. Intussusception is not primarily an inflammatory process; instead, it is a mechanical issue involving bowel invagination.
Choice A is incorrect as it does not accurately describe the pathophysiology of intussusception.
Choice C is incorrect because it presents the opposite scenario of what happens in intussusception.
