Correct Answer: D

Rationale: The correct answer is to have the client use a trapeze bar when changing positions. This action helps in repositioning without causing friction or shearing, which can lead to skin breakdown. Placing the client in high-Fowler's position (Choice A) may not directly prevent skin breakdown related to limited mobility. Increasing carbohydrate intake (Choice B) is not relevant to preventing skin breakdown. Massaging reddened areas with lotion (Choice C) can potentially cause more harm by increasing friction and damaging the skin further, rather than preventing breakdown.

Correct Answer: A

Rationale: The correct action for the nurse to take when a client has a prescription for a 24-hour urine collection is to discard the first voiding. This initial voiding is typically not collected to allow for the accurate start of the 24-hour collection period. All subsequent urine voided within the specified time frame is then collected. Including the last voiding in the collection is important to ensure that the full 24-hour period is covered. It is essential to keep the urine cool by storing it in a single container on ice to prevent degradation of components. Instructing the client to stop midstream and finish urinating into the specimen container is not required for a 24-hour urine collection and is an unnecessary step.

Correct Answer: A

Rationale: To administer 4 mg of morphine, as prescribed, the LPN/LVN needs to calculate the correct volume based on the concentration provided (8 mg per ml). Since the desired dose is 4 mg, half of 8 mg (0.5 ml) is required to administer the correct amount. Therefore, the correct answer is 0.5 ml. Choices B, C, and D are incorrect as they would either underdose or overdose the patient.

Correct Answer: B

Rationale: The correct placement to auscultate the aortic valve is at the second intercostal space to the right of the sternum, which coincides with the aortic area. The choice stating 'Fifth intercostal space at the midclavicular line' is the correct answer for auscultating the aortic valve. Placing the stethoscope at the left sternal border would be more suitable for listening to the tricuspid valve. The fifth intercostal space at the anterior axillary line is the recommended area for auscultating the mitral valve. Therefore, choice B is the correct answer for assessing the aortic valve in a client with a history of a heart murmur related to aortic valve stenosis.

Correct Answer: C

Rationale: The correct answer is C: Pain with passive movement. Pain with passive movement in a client with a new cast can indicate compartment syndrome, a serious condition where pressure builds up within the muscles, nerves, and blood vessels of the affected limb, potentially leading to tissue damage. Immediate reporting is crucial to prevent further complications. Increased warmth in the affected arm could be a normal inflammatory response to the injury and casting process. Itching under the cast is common and can be managed without immediate concern. Drainage on the cast may be expected initially after casting due to residual moisture from the setting process, but ongoing or excessive drainage should be monitored and reported if persistent.
