Correct Answer: C

Rationale: During nasotracheal suctioning, the client gagging during the procedure is a cause for concern as it can indicate discomfort or potential airway obstruction. Cyanosis, bloody secretions, or the removal of clear to opaque secretions are expected observations that the nurse should monitor for, but gagging indicates a need for immediate intervention to ensure the safety and comfort of the client. Cyanosis and bloody secretions can signify oxygenation issues and potential complications, while the removal of secretions is the goal of the suctioning procedure.

Correct Answer: A

Rationale: When erythromycin and cefaclor are taken together, erythromycin can inhibit the metabolism of cefaclor, leading to elevated cefaclor levels and potentially causing adverse effects. This results in a decrease in the effectiveness of cefaclor. Therefore, the nurse should discuss this potential drug interaction with the provider to consider an alternative treatment or adjust the dosages to prevent complications. Choices B, C, and D are incorrect because the concern lies with the effect on cefaclor when combined with erythromycin, not the effect on erythromycin itself.

Correct Answer: A

Rationale: The correct answer is A. A Pap smear cannot be performed with accurate results during menstruation. Menstrual blood may interfere with the test results. Choice B is incorrect as vaginal douching should be avoided for at least 24 hours before the test to prevent altering the cervical cells. Choice C is incorrect as there is no restriction on spicy foods before a Pap smear. Choice D is incorrect as some women may experience mild discomfort during the test, although it is generally well-tolerated.

Correct Answer: B

Rationale: Serum bilirubin is the most specific indicator of hepatitis as it reflects liver dysfunction. Hemoglobin, blood urea nitrogen (BUN), and erythrocyte sedimentation rate (ESR) are not specific to hepatitis. Hemoglobin measures the oxygen-carrying capacity of red blood cells, BUN evaluates kidney function, and ESR is a nonspecific marker of inflammation or infection.

Correct Answer: A

Rationale: Choice A, 'I am thrilled that I can continue to eat fast food,' indicates a lack of understanding as fast food is typically high in sodium, which is detrimental for individuals with CKD. The client should be advised to avoid fast food due to its high sodium content. Choices B, C, and D demonstrate a good understanding of the need for sodium restriction in the diet to prevent complications associated with CKD. Cutting out bacon, avoiding salt in cooking, and eliminating high-sodium snacks like potato chips are all positive steps towards managing CKD.
