A nurse is caring for a client who has fluid volume deficit and is receiving a continuous IV infusion. Which of the following findings indicates the treatment has been effective?
Elastic skin turgor
Dry mucous membranes
Oliguria
Tachycardia
The Correct Answer is A
Choice A reason: Elastic skin turgor is a sign of adequate hydration and fluid balance. Skin turgor is the ability of the skin to return to its normal shape after being pinched or pulled. When the skin is dehydrated, it loses its elasticity and becomes tented or wrinkled. The nurse should assess the skin turgor on the chest, abdomen, or forehead, and not on the hands or feet, which can be affected by aging or edema.
Choice B reason: Dry mucous membranes are a sign of fluid volume deficit, not fluid volume excess. Mucous membranes are the moist linings of the mouth, nose, eyes, and other body openings. When the body is dehydrated, the mucous membranes become dry, cracked, or sticky. The nurse should assess the mucous membranes for color, moisture, and capillary refill.
Choice C reason: Oliguria is a sign of fluid volume deficit, not fluid volume excess. Oliguria is the production of abnormally small amounts of urine, usually less than 400 mL per day or 30 mL per hour. Oliguria can indicate reduced kidney function, impaired blood flow to the kidneys, or inadequate fluid intake. The nurse should monitor the urine output, color, specific gravity, and presence of blood or protein.
Choice D reason: Tachycardia is a sign of fluid volume deficit, not fluid volume excess. Tachycardia is a rapid heart rate, usually more than 100 beats per minute. Tachycardia can occur when the body is dehydrated, as the heart tries to pump more blood to maintain the blood pressure and perfusion. The nurse should measure the pulse rate, rhythm, quality, and amplitude.

Correct Answer is B
Explanation
Choice A reason: Anticholinesterase medications should be taken 30 minutes before meals, not with meals. This is because they enhance the action of acetylcholine, which improves muscle strength and swallowing ability.
Choice B reason: Positioning the head of the client's bed to 40° while eating helps prevent aspiration and facilitates swallowing. This is the best action for the nurse to take for a client who has myasthenia gravis.
Choice C reason: Encouraging the client to lie down after eating is not advisable, as it increases the risk of aspiration and reflux. The client should remain upright for at least 30 minutes after eating.
Choice D reason: Providing the client with food cut into small bites is not enough to ensure safe and adequate nutrition. The client may still have difficulty swallowing and chewing. The nurse should also offer soft, moist, and easy-to-swallow foods, and avoid foods that are dry, sticky, or hard.
Correct Answer is A
Explanation
Choice A reason: Prealbumin is a protein that is synthesized by the liver and reflects the current nutritional status of the client. It has a short half-life of 2 to 3 days, which makes it a sensitive indicator of changes in protein intake. Prealbumin levels are decreased in clients who are malnourished or have inflammation, infection, or liver disease. The nurse should monitor the prealbumin levels of the client who is receiving total parenteral nutrition to ensure that they are within the normal range of 15 to 36 mg/dL.
Choice B reason: Folic acid is a water-soluble vitamin that is involved in DNA synthesis, cell division, and red blood cell production. Folic acid levels are decreased in clients who have malabsorption, alcoholism, or certain medications, such as methotrexate or phenytoin. The nurse should assess the folic acid levels of the client who is receiving total parenteral nutrition, but it is not the priority test to confirm adequate nutrition.
Choice C reason: Magnesium is a mineral that is involved in many enzymatic reactions, muscle contraction, nerve transmission, and bone formation. Magnesium levels are decreased in clients who have malnutrition, diarrhea, vomiting, or diuretic use. The nurse should evaluate the magnesium levels of the client who is receiving total parenteral nutrition, but it is not the priority test to confirm adequate nutrition.
Choice D reason: Transferrin is a protein that transports iron in the blood and reflects the iron stores of the client. Transferrin levels are decreased in clients who have iron deficiency anemia, chronic disease, or liver disease. The nurse should check the transferrin levels of the client who is receiving total parenteral nutrition, but it is not the priority test to confirm adequate nutrition.
