The nurse would select the dorsal venous plexus of the foot as an IV site for which patient?

A 22-year-old adult.

A 50-year-old patient.

A 2-year-old child.

An 80-year-old patient.

Answer and Explanation

The Correct Answer is C

Rationale:
A. A 22-year-old adult would typically have IV access placed in the veins of the upper extremities (hand or forearm), not the foot.
B. A 50-year-old patient would not be an appropriate candidate for a foot IV, as peripheral veins in the arms are preferred and safer.
C. A 2-year-old child is correct because the dorsal venous plexus of the foot is often used in infants and young children when veins in the hands or arms are small, fragile, or difficult to access.
D. An 80-year-old patient would be at increased risk of poor circulation and delayed healing in the feet, making this site inappropriate.

Correct Answer is C

Explanation

Rationale:
A. Examining the nares for patency and skin breakdown is important for safety but does not directly reduce discomfort during insertion.
B. Placing the patient in high-Fowler’s position promotes safe passage and reduces aspiration risk, but it does not specifically relieve discomfort.
C. Anesthetizing the throat (e.g., with a topical anesthetic spray or viscous lidocaine) can numb the mucosa, significantly reducing discomfort during NG tube insertion.
D. Having the patient sip water helps advance the tube once insertion has started, but it does not reduce the initial discomfort of tube passage.

A. The degree to which medications bind to serum proteins, which affects distribution. B. The method by which a medication, after absorption, is moved within the body to tissues, organs, and specific sites of action. C. The passage of medication molecules into the blood from the site of administration. D. The study of how medications enter the body, reach their site of action, are metabolized, and exit the body.

Correct Answer is D

Explanation

Rationale:
A. This describes protein binding, which is one factor affecting drug distribution, but it is not the full definition of pharmacokinetics.
B. This describes distribution, which is one phase of pharmacokinetics.
C. This describes absorption, which is another phase of pharmacokinetics.
D. Pharmacokinetics is the study of how medications enter the body, move to their site of action, are metabolized, and are eliminated. It encompasses absorption, distribution, metabolism, and excretion.
