The client receives nystatin (Nilstat) for a fungal infection in the mouth. The nurse plans to do medication education prior to discharge. What will the best plan by the nurse include?

Correct Answer: A

Rationale: Nystatin treats oral thrush by direct mucosal contact, requiring the tablet to dissolve in the mouth for prolonged exposure before swallowing. This maximizes antifungal action against Candida. Using a straw might apply to suspensions but isn't standard for discoloration prevention, which isn't a primary issue. Crushing and mixing with juice reduces contact time, decreasing efficacy. Swallowing whole bypasses the infection site, rendering it ineffective. The nurse's best plan educates on dissolving the tablet, aligning with nystatin's topical mechanism, ensuring treatment success and preventing recurrence, making A the optimal instruction.

Correct Answer: D

Rationale: Warfarin is an anticoagulant medication that works by inhibiting vitamin K-dependent clotting factors in the body. Overdosing on warfarin can lead to excessive bleeding due to the lack of functional clotting factors. To reverse the effects of warfarin overdose, Vitamin K is given because it helps the body restore the levels of clotting factors that were reduced by warfarin. Vitamin K promotes the synthesis of clotting factors II, VII, IX, and X, which allows the blood to clot effectively again. Therefore, in the case of a warfarin overdose, Vitamin K is the appropriate antidote to help reverse the anticoagulant effects.

Correct Answer: C

Rationale: When a patient is receiving diuretic therapy, monitoring intake, output, and daily weight is essential in assessing the patient's fluid volume status. Diuretics promote the excretion of excess fluid from the body, which can lead to changes in fluid balance. Monitoring intake and output provides information about how much fluid the patient is taking in and how much is being excreted, helping to assess the overall fluid balance. Daily weight measurements can also indicate changes in fluid status, as a sudden weight gain or loss may suggest fluid retention or depletion, respectively. Additionally, trends in weight changes over time can provide valuable information about the effectiveness of diuretic therapy and the patient's response to treatment.

Correct Answer: B

Rationale: Systemic corticosteroids (e.g., prednisone) for ulcerative colitis cause side effects. Osteoporosis results from reduced bone formation over time. Diabetes stems from glucocorticoid-induced hyperglycemia. Hypertension occurs via sodium retention and vasoconstriction. Mood changes are common due to CNS effects. Weight loss isn't typical; corticosteroids cause weight gain from increased appetite and fat redistribution, making it the exception. This reflects their metabolic impact, requiring monitoring in chronic use.

Correct Answer: C

Rationale: Oseltamivir treats influenza by inhibiting neuraminidase . This prevents viral release from infected cells, reducing spread. M2 blockade is amantadine's action. IMP dehydrogenase , reverse transcriptase , and DNA polymerase (E) are unrelated. Neuraminidase inhibition shortens his illness.
