Question 4 of 5
A nurse administers a dose of an oral medication for hypertension to a patient who immediately vomits after swallowing the pill. What action will the nurse take first?
Correct Answer: C
Rationale: If a patient vomits immediately after swallowing an oral pill, the nurse should assess the emesis (vomit) for the pill or fragments of it. The nurse will collaborate with the health care provider to determine if another dose should be administered.
Question 5 of 5
A nurse caring for a group of patients uses measures to reduce discomfort for the patients during injections. Which technique is recommended?
Correct Answer: C
Rationale: The nurse should use the Z-track technique for intramuscular injections to prevent medication from leaking into the needle track, minimizing discomfort. The nurse should select a needle of the smallest gauge that is appropriate for the site and solution to be injected, and select the correct needle length for the type of injection and patient size. The nurse should inject the medication into relaxed muscles since more pressure (causing discomfort) will be required to injected into contracted muscles. The nurse should apply gentle pressure after injection, unless this technique is contraindicated.
