Correct Answer: A

Rationale: Long-term protein deficiency significantly lowers serum albumin levels. Albumin, derived from protein breakdown, is produced by the liver when adequate amino acids are available. Due to its long half-life, acute protein loss minimally affects serum albumin levels. In contrast, serum transferrin, with a shorter half-life of 8 to 10 days, decreases with acute protein deficiency and is not a reliable indicator of chronic protein malnutrition. Elevated hemoglobin levels may occur in conditions like dehydration or chronic obstructive pulmonary disease, making it an unreliable indicator of chronic protein malnutrition. High cholesterol levels are not directly linked to protein malnutrition and do not serve as a reliable indicator.
Therefore, the most reliable indicator of chronic protein malnutrition among the options provided is a low serum albumin level.

Correct Answer: B

Rationale:
To ensure optimal benefits from a metered-dose inhaler, the client should be instructed to compress the inhaler while slowly breathing in through the mouth. This technique facilitates the medication to reach deep into the lungs, allowing for an optimal bronchodilation effect. Option B is correct as it promotes the proper coordination of inhaler compression and inhalation, ensuring effective drug delivery. Options A, C, and D are incorrect as they do not support deep lung penetration of the medication, which is essential for its effectiveness in treating respiratory conditions.

Correct Answer: B

Rationale: Clients with cholecystitis, which is inflammation of the gallbladder, should follow a low-fat diet to reduce symptoms. Broiled fish, green beans, and an apple (Option
B) is the most suitable choice as it is low in fat. Steak, baked beans, and a salad (Option
A) provide a high amount of fat and protein, which may exacerbate symptoms of cholecystitis. Pork chops, macaroni and cheese, and grapes (Option
C) and avocado salad, milk, and angel food cake (Option
D) contain high-fat foods that are not recommended for individuals with cholecystitis.
Therefore, Option B is the most appropriate choice for a client with cholecystitis.

Correct Answer: A

Rationale: The most crucial action for the nurse to implement when obtaining a lie-sit-stand blood pressure reading is to stay with the client while the client is standing. This is essential to monitor the client's immediate response to position changes and ensure their safety. Recording the findings on the graphic sheet is important for documentation but is not as critical as staying with the client. Keeping the blood pressure cuff on the same arm helps maintain consistency in readings but is not as vital as ensuring client safety. Recording changes in the client's pulse rate is important for a comprehensive assessment but does not take precedence over monitoring the client during position changes.

Correct Answer: D

Rationale: The best method for the nurse to evaluate the client's ability to perform a dressing change at home is by observing the client change the dressing unassisted. Direct observation allows the nurse to assess if the client has mastered the skill and provides an opportunity to confirm the proficiency. Options A, B, and C do not offer the same level of assessment as direct observation. Option A incorrectly focuses on the client's feelings rather than their actual performance ability. Option B, asking the client to demonstrate the procedure, may not accurately reflect their practical skills. Option C, seeking a family member's opinion, introduces potential bias and may not provide an accurate assessment of the client's ability to perform the dressing change independently.
