1. The nurse is caring for a patient in metabolic alkalosis. The patient has an NG tube to low intermittent suction for a diagnosis of bowel obstruction. What drug would the nurse expect to find on the medication orders?

• A. Cimetidine
• B. Maalox
• C. Potassium chloride elixir
• D. ) Furosemide

Correct answer: A

Rationale:

2. The nurse assessing skin turgor in an elderly patient should remember that:

• A. Overhydration causes the skin to tent.
• B. Dehydration causes the skin to appear edematous and spongy.
• C. Inelastic skin turgor is a normal part of aging.
• D. Normal skin turgor is moist and boggy.

Correct answer: C

Rationale: Inelastic skin turgor is a normal part of aging. Dehydration, not overhydration, causes inelastic skin with tenting. Overhydration, not dehydration, causes the skin to appear edematous and spongy. Normal skin turgor is dry and firm. Choice A is incorrect because overhydration does not cause the skin to tent; it is dehydration that leads to tenting. Choice B is incorrect because dehydration, not overhydration, causes the skin to appear edematous and spongy. Choice D is incorrect because normal skin turgor is dry and firm, not moist and boggy.

3. The renin and angiotensin systems help to maintain the balance of sodium and water in the body. What other functions do these systems serve?

• A. Regulating hemoglobin levels
• B. Maintaining a healthy blood volume
• C. Releasing platelets when tissues are injured
• D. Lowering blood volumes

Correct answer: B

Rationale: The correct answer is B: Maintaining a healthy blood volume. The renin and angiotensin systems not only help to regulate sodium and water balance in the body but also play a crucial role in maintaining an adequate blood volume. This is essential for normal blood pressure regulation and overall cardiovascular health. Choices A, C, and D are incorrect because hemoglobin levels are primarily regulated by the bone marrow and erythropoietin, platelets are released in response to blood vessel injury by a different mechanism, and the systems do not focus on lowering blood volumes but rather on maintaining them.

4. You are doing discharge teaching with a patient who has hypophosphatemia during his time in hospital. The patient has a diet ordered that is high in phosphate. What foods would you teach this patient to include in his diet? Select all that do not apply

5. The physician has ordered a peripheral IV to be inserted before the patient goes for computed tomography. What should the nurse do when selecting a site on the hand or arm for insertion of an IV catheter?

• A. Choose a site with minimal hair if available.
• B. Consider potential effects on the patient's mobility when selecting a site.
• C. Instruct the patient to hold his arm in a dependent position before insertion.
• D. Remove the tourniquet after 2 minutes.

Correct answer: B

Rationale: When selecting a site for IV insertion on the hand or arm, it is important to consider the potential effects on the patient's mobility. The chosen site should not interfere with the patient's movement. Instructing the patient to hold his arm in a dependent position helps increase blood flow, aiding in vein visualization and insertion. It is advisable to choose a site with minimal hair if possible for better adhesion of the dressing. Removing the tourniquet after 2 minutes is recommended to prevent complications like hemoconcentration and potential vein damage. Therefore, option B is the correct choice as it aligns with best practices for IV insertion.
