Correct Answer: A

Rationale: In this scenario, the nurse is performing the assessment phase of the nursing process. Assessment involves collecting data, which includes obtaining vital signs, to identify the client's health status and needs. This step is crucial for the nurse to gather information that will guide further decision-making in the nursing process.

Correct Answer: B

Rationale: Buccal medication is administered by placing it between the client's cheeks and gums. This route allows for the medication to be absorbed through the mucous membranes in the mouth, providing a rapid onset of action compared to oral ingestion. Placing the medication under the tongue (sublingual) allows for absorption through the sublingual mucosa, not the buccal mucosa. Placing medication on the skin or the conjunctiva is not appropriate for buccal administration.

Correct Answer: C

Rationale: When a client has difficulty swallowing capsule medication, the nurse should check the availability of a liquid preparation. This is a safer approach and ensures that the medication's integrity is maintained, providing an alternative form that is easier for the client to take.

Correct Answer: B

Rationale: 1 cc (cubic centimeter) is equal to 1 ml. Therefore, 20 cc is equal to 20 ml. To convert between cubic centimeters (cc) and milliliters (ml), the values are equivalent, as they both measure volume in the metric system.

Correct Answer: D

Rationale: The Z-track technique is the best action to prevent tracking of the medication when administering an IM injection that is irritating to the subcutaneous tissue. This technique involves pulling the skin to the side before administering the injection and then releasing the skin after the injection. By doing so, a zig-zag pathway is created, preventing the medication from leaking into the subcutaneous tissue and reducing irritation.
