Nursing Elites

1. Neomycin may decrease absorption of which nutrient?

• A. Iron, copper, and zinc
• B. Protein and amino acids
• C. Fat-soluble vitamins
• D. Water-soluble vitamins

Correct answer: C

Rationale: The correct answer is C: Fat-soluble vitamins. Neomycin is known to interfere with the absorption of fat-soluble vitamins. This is because neomycin can disrupt the normal gut flora responsible for the absorption of these vitamins. Choices A, B, and D are incorrect because neomycin primarily affects the absorption of fat-soluble vitamins, not minerals, proteins, amino acids, or water-soluble vitamins.

2. Which of the following describes a process of heat loss involving the transfer of heat from one surface to another?

• A. Radiation
• B. Conduction
• C. Convection
• D. Evaporation

Correct answer: B

Rationale: Conduction is the process of heat transfer that occurs between objects or substances that are in direct contact with each other. In this process, heat is transferred from a hotter surface to a cooler surface through direct contact. This type of heat transfer does not involve the movement of the substances themselves, only the transfer of thermal energy. Choice A, Radiation, is the transfer of heat in the form of electromagnetic waves and does not require a medium. Choice C, Convection, involves the transfer of heat through the movement of fluids (liquids or gases) due to density differences. Choice D, Evaporation, is a cooling process that involves the transformation of a liquid into a gas, absorbing heat in the process.

3. Which of the following nursing interventions is important for a client scheduled to have a Guaiac Test?

• A. Avoid turnips, radish, and horseradish 3 days before
• B. Continue iron preparation to prevent further loss
• C. Do not consume meat 12 hours before the procedure
• D. Encourage consumption of caffeine and dark-colored foods

Correct answer: A

Rationale: The correct answer is A. Turnips, radish, and horseradish are known to cause false-positive results in a Guaiac Test, which is used to detect blood in the stool. Avoiding these foods is crucial to ensure accurate test results. Choice B is incorrect as iron preparation is not directly related to the Guaiac Test. Choice C is incorrect because avoiding meat is not specifically necessary before a Guaiac Test. Choice D is incorrect as caffeine and dark-colored foods can potentially interfere with test results, so they should not be encouraged.

4. Which lipoprotein carries cholesterol from tissues to the liver for excretion?

• A. Very low-density lipoprotein
• B. Intermediate-density lipoprotein
• C. Low-density lipoprotein
• D. High-density lipoprotein

Correct answer: D

Rationale: The correct answer is D, High-density lipoprotein (HDL). HDL is known as 'good' cholesterol because it helps transport excess cholesterol from tissues back to the liver for removal from the body. Very low-density lipoprotein (VLDL) (choice A) and intermediate-density lipoprotein (choice B) are involved in transporting triglycerides. Low-density lipoprotein (LDL) (choice C) is known as 'bad' cholesterol as it can deposit cholesterol in the walls of arteries.

5. When measuring the leg circumference of a client with bipedal edema, what position is best to ensure accurate measurements?

• A. Dorsal recumbent
• B. Sitting
• C. Standing
• D. Supine

Correct answer: A

Rationale: When measuring the leg circumference of a client with bipedal edema, the best position to ensure accurate and consistent measurements is the dorsal recumbent position. This position allows the legs to be positioned comfortably, and the individual is lying on their back with legs extended, facilitating accurate measurement of the circumference without the influence of gravity. Sitting, standing, and supine positions may not provide optimal conditions for accurate leg circumference measurements, particularly in clients with bipedal edema where positioning and consistency are crucial. Sitting and standing positions may not allow for consistent leg positioning and could introduce errors due to the effects of gravity on the fluid distribution. The supine position, while similar to dorsal recumbent, may not be as comfortable for the client and could still be influenced by gravity when measuring leg circumference.
