A healthcare professional is preparing to administer a subcutaneous injection of insulin. Which of the following actions should the professional take?

Correct Answer: B

Rationale: When administering a subcutaneous injection, inserting the needle at a 90-degree angle is appropriate. This angle helps ensure proper delivery of the medication into the subcutaneous tissue. Using a 1-inch needle is common for subcutaneous injections to reach the subcutaneous fat layer adequately. Tuberculin syringes are typically used for intradermal injections, not subcutaneous injections. Aspirating before injecting is not necessary for subcutaneous injections as it is primarily used for intramuscular injections to ensure the needle is not in a blood vessel.

Correct Answer: B

Rationale: Monitoring weight daily is crucial when taking furosemide to detect fluid retention or loss. Furosemide is a diuretic that helps the body get rid of excess water and salt through urine. Changes in weight can indicate fluid shifts, which could be a sign of inadequate response to the medication or worsening condition. Therefore, monitoring weight daily is essential to assess the effectiveness of furosemide therapy and detect any potential issues early on. Choices A, C, and D are incorrect. Avoiding foods high in potassium is more relevant for clients taking potassium-sparing diuretics, not furosemide. Taking furosemide with food is not necessary, as it can be taken with or without food. Increasing salt intake is contradictory to the purpose of furosemide, which aims to eliminate excess salt from the body.

Correct Answer: D

Rationale: When collecting a stool specimen for ova and parasites, it is essential to place the specimen collection container in a biohazard bag. This practice ensures proper handling of potentially infectious material and prevents contamination with microorganisms. The biohazard bag should be labeled with the client's information for easy identification and proper tracking throughout the testing process. Instructing the client to defecate into a clean container is incorrect as it may introduce contaminants. Transferring the specimen to a sterile container is unnecessary and can increase the risk of contamination. Refrigerating the collected specimen is also not recommended as it may alter the sample and affect the test results.

Correct Answer: A

Rationale: Hyperoxygenating the client before suctioning is crucial to prevent hypoxia during the procedure. By using a manual resuscitation bag with 100% oxygen, the nurse should provide several breaths to the client to ensure sufficient oxygenation before starting suctioning. This approach helps maintain oxygen levels and decreases the risk of hypoxia, which may arise when suctioning interrupts the normal respiratory process. Choices B, C, and D are incorrect because inserting the catheter during exhalation, applying suction while inserting the catheter, and limiting suctioning to 15 seconds do not address the priority of hyperoxygenating the client to prevent hypoxia.

Correct Answer: C

Rationale: The correct answer is C: Lentils. Incomplete proteins lack one or more essential amino acids required for protein synthesis in the body. Examples of incomplete proteins include lentils, vegetables, grains, nuts, and seeds. Lentils, a plant-based protein source, are considered incomplete as they do not contain all essential amino acids in sufficient amounts. Choices A, B, and D are incorrect as eggs, soybeans, and yogurt are examples of complete proteins, containing all essential amino acids in the right proportions for the body's needs.
