ACE inhibitors…
- A. Block the vasoconstrictor and aldosterone from producing effects of angiotensin II at the receptor site
- B. Blocks stimulation of beta 1 and beta 2 at the receptor sites
- C. Blocks the conversion of angiotensin I to the vasoconstrictor angiotensin II
- D. None of the above
Correct Answer: A
Rationale: ACE inhibitors, such as enalapril and lisinopril, work by blocking the enzyme angiotensin-converting enzyme (ACE), which is responsible for converting angiotensin I into angiotensin II. By inhibiting this conversion, ACE inhibitors prevent the vasoconstrictor and aldosterone-stimulating effects of angiotensin II at the receptor sites. This leads to vasodilation, decreased blood pressure, and reduced aldosterone secretion. This mechanism of action makes ACE inhibitors an important class of medications for managing conditions such as hypertension, heart failure, and chronic kidney disease.

An adolescent client will receive Depo-Provera as a method of birth control. She asks the nurse how long the drug will be effective. What is the best response by the nurse?
- A. 2 months
- B. 6 months
- C. 1 year
- D. 3 months
Correct Answer: D
Rationale: Depo-Provera, a progestin injection, provides contraception by inhibiting ovulation for 3 months , requiring re-administration every 12 weeks. This duration is based on its pharmacokinetic profile, ensuring reliable hormone levels. Two months underestimates, risking unprotected gaps. Six months or 1 year overestimate, reducing efficacy mid-cycle. The nurse's accurate response (D) educates the client on timing, ensuring adherence and preventing unintended pregnancy, aligning with clinical standards for injectable contraceptives.

Notifying the healthcare provider (B) may be necessary if the patient cannot tolerate the medication.
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.

- C.
- D. Apply the patch to hairless areas of the body.
Correct Answer: D
Rationale: Transdermal nitroglycerin patches should be applied to clean, dry, hairless areas of the body to ensure proper absorption of the medication. Hair can interfere with the absorption of the medication through the skin. Commonly recommended areas for application include the chest, upper arm, or abdomen. It is important to rotate application sites to prevent skin irritation and to follow the specific instructions provided by the healthcare provider or pharmacist.

- B. Pregnancy is not contraindicated with the use of the medication.
- C. Strict hand washing.
- D. Get a daily source of sunlight during the day.
Correct Answer: C
Rationale: Methotrexate is an immunosuppressant, increasing the risk of infections. Strict hand washing and infection prevention measures are crucial. Clay-colored stools are not normal and may indicate liver dysfunction. Pregnancy is contraindicated due to the risk of fetal harm. Sunlight exposure should be limited to reduce the risk of photosensitivity reactions.
