Why is it important to monitor ins and outs with patients using ACE inhibitors?
- A. To assess for renal impairment
- B. You must make sure the patient is receiving adequate fluid intake
- C. To assess the patient for potential heart failure
- D. To assess for decreased blood pressure
Correct Answer: D
Rationale: It is important to monitor ins and outs with patients using ACE inhibitors to assess for decreased blood pressure. ACE inhibitors are known to lower blood pressure by dilating blood vessels, which can sometimes lead to hypotension (low blood pressure). Monitoring the patient's fluid intake and output helps healthcare providers evaluate the patient's blood pressure response to the medication and make necessary adjustments to prevent complications such as dizziness, falls, or fainting. Regular monitoring is crucial to ensure the patient's safety and optimize the effectiveness of ACE inhibitor therapy.
Depression that occurs during cold winter months would be classified as
- A. baby blues
- B. bipolar disorder
- C. seasonal affective disorder
- D. obsessive-compulsive disorder
Correct Answer: C
Rationale: Seasonal affective disorder (SAD) ties depression to winter-less light, per psychiatry-unlike baby blues (postpartum), bipolar (cycles), or OCD (obsessions). SAD's seasonal link defines it, matching symptoms.
What is a side effect of Heparin?
- A. nausea
- B. diarrhea
- C. bleeding
- D. bronchospasms
Correct Answer: C
Rationale: A common side effect of Heparin, which is an anticoagulant medication, is the risk of bleeding. Heparin works by preventing the formation of blood clots, which can lead to a bleeding risk as it inhibits the normal clotting process. Patients taking Heparin should be monitored closely for signs of bleeding, such as easy bruising, prolonged bleeding from minor cuts, or blood in the urine or stools. It is important for healthcare providers to closely monitor patients on Heparin therapy and adjust the dosage as needed to minimize the risk of excessive bleeding.
A nurse is providing administration instruction to the wife of a client going home on intermittent enteral nutrition. Which information should the nurse include?
- A. Clean the equipment between each feeding administration
- B. Once mixed, enteral feeding should hang no more than 8 hours
- C. Refrigerate any feeding that is not needed for a feeding
- D. Keep the area around the insertion site clean
Correct Answer: A
Rationale: Cleaning equipment between each enteral feeding is vital to prevent bacterial contamination, as residual formula can foster microbial growth, risking infections like gastroenteritis in a client already nutritionally compromised. While limiting hang time is important, evidence suggests a 4-hour maximum, not 8, to minimize spoilage-though this isn't the focus here. Refrigerating unused feeding preserves its integrity, preventing degradation or bacterial proliferation, which is critical for safety. Keeping the insertion site clean reduces infection risk at the tube entry, a common complication in enteral therapy. Cleaning equipment stands out as a proactive step the wife can take between feedings, directly impacting hygiene and client safety, whereas other points address storage or site care, which, while essential, are secondary to the immediate post-feeding action of equipment maintenance in this context.
A 48-year-old woman pricks her finger on a rose bush while pruning. A few days later, she develops small, red lesions near the wound and a red track ascending her hand toward her trunk. Her doctor prescribes itraconazole for the sporotrichosis. What is the mechanism of action of this medication?
- A. Disrupts fungal cell membrane by forming pores (nystatin, amphotericin B)
- B. Disrupts fungal microtubules (griseofulvin)
- C. Inhibits conversion of lanosterol to ergosterol
- D. Inhibits squalene monooxygenase (terbinafine)
Correct Answer: C
Rationale: Sporotrichosis, from Sporothrix schenckii, requires antifungals like itraconazole. Option , inhibiting lanosterol to ergosterol conversion, is correct-itraconazole blocks 14-α-demethylase, disrupting fungal membrane synthesis. Option , pore formation, is amphotericin B's mechanism. Option , microtubule disruption, is griseofulvin's. Option , squalene monooxygenase inhibition, is terbinafine's. Option (E), 5-FU conversion, is flucytosine's. Itraconazole's ergosterol inhibition effectively treats this subcutaneous infection, targeting fungal viability.
