Correct Answer: D

Rationale: To prevent venous thrombus formation, promoting venous return is crucial. Encouraging frequent ambulation in the hallway helps prevent venous stasis and reduces the risk of thrombus formation in immobile clients. Option A (using the incentive spirometer) aids in alveolar expansion to prevent atelectasis, not specifically venous thrombosis. Option B (elevating the head of the bed during meals) reduces the risk of aspiration, not venous thrombosis. Option C (using aseptic technique for dressing changes) reduces the risk of postoperative infection, not specifically venous thrombosis. Therefore, among the options provided, encouraging frequent ambulation in the hallway is the most effective measure to prevent venous thrombosis.

Correct Answer: C

Rationale: Encouraging the adolescent client to talk about her view of herself is the first action the nurse should take. Body image is crucial for adolescents, especially after pregnancy. By addressing the client's concerns about her weight and discussing her self-perception, the nurse can provide emotional support and open a dialogue for further assessment and teaching. Choice A, 'Review the client's weight pattern over the year,' is not the priority at this time as the client's immediate concern is her post-pregnancy weight. Choice B, 'Ask the mother to record her diet for the last 24 hours,' focuses on dietary habits rather than addressing the client's emotional concerns. Choice D, 'Give her several pamphlets on postpartum nutrition,' may be helpful but should come after addressing the client's emotional needs and concerns.

Correct Answer: B

Rationale: Option B is the correct procedure for assisting a client from the bed to a chair. By positioning the nurse's feet apart and aligning the knees with the client's knees, the nurse maintains a stable base of support while pivoting the client into the chair. This technique minimizes the risk of injury to both the nurse and the client. Placing the chair at a 45-degree angle to the bed, with the back of the chair toward the head of the bed, provides a clear path for the client to move. Option C is incorrect because lifting a client under the axillae can potentially cause nerve damage and strain. Option D is also incorrect as it involves an unsafe method of moving the client and can lead to injuries or accidents.

Correct Answer: D

Rationale: The nurse should monitor the client's serum sodium levels carefully when they have been on nasogastric (NG) tube suction for an extended period. Prolonged NG suctioning can lead to fluid loss and subsequent hyponatremia. Monitoring sodium levels is crucial to prevent complications. White blood cell count (Option A), albumin (Option B), and calcium (Option C) are not typically affected by prolonged NG suctioning. Therefore, these values are not the priority for monitoring in this situation.

Correct Answer: A

Rationale: Barbiturates cause central nervous system (CNS) depression, increasing the risk of falls. Therefore, the nurse should assist the client to the bathroom to ensure safety. Using a bedpan is not necessary if the client can safely walk to the bathroom. Asking about bowel movements or voiding, as in option C, is irrelevant to the immediate safety concern of assisting the client to the bathroom. Assessing the client's bladder, as in option D, is unnecessary in this situation as there is no indication that the client cannot communicate his or her needs effectively. The priority here is to prevent falls and ensure the client's safety while assisting to the bathroom.
