The nurse understands that which of the ff. best describes the action of enalapril maleate (Vasotec)?
- A. It decreases levels of angiotensin II
- B. It dilates the arterioles and veins
- C. It adjusts the extracellular volume
- D. It decreases cardiac output
Correct Answer: A
Rationale: Enalapril maleate (Vasotec) is an angiotensin-converting enzyme (ACE) inhibitor. The main action of ACE inhibitors like enalapril is to decrease the levels of angiotensin II in the body. Angiotensin II is a potent vasoconstrictor that plays a role in regulating blood pressure, stimulating aldosterone secretion, and promoting sodium and water retention. By inhibiting the conversion of angiotensin I to angiotensin II, enalapril reduces vasoconstriction and aldosterone secretion, leading to vasodilation, decreased blood pressure, and ultimately decreased levels of angiotensin II. This mechanism allows for the dilation of arterioles and veins, reduction in cardiac afterload, and ultimately decreases the workload of the heart.
For children receiving steroid therapy, which of the following regimens is most appropriate for perioperative management?
- A. Prednisone 1 mg/kg given 24 and 12 hours before surgery
- B. Dexamethasone 0.6 mg/kg IV given 24 and 12 hours before surgery
- C. Hydrocortisone 5 mg/kg IV given 24 and 12 hours before surgery
- D. Methylprednisolone 10 mg/kg IV given 24 and 12 hours before surgery
Correct Answer: C
Rationale: Hydrocortisone is commonly used for perioperative steroid coverage due to its mineralocorticoid and glucocorticoid effects.
Thirty minutes after the nurse removes a nasogastric tube that has been In place for seven days, the patient experiences epistaxis (nosebleed). Which of the following nursing actions is most appropriate to control the bleeding? a.Apply pressure by pinching the anterior portion of the for five to ten minutes
- A. Place the patient in a sitting position with the neck hyperextended
- B. Pack the nostrils with gauze and keep the gauze in piace for four to five days
- C. Apply ice compresses to the patient's forehead and back of the neck
Correct Answer: A
Rationale: The most appropriate nursing action to control the bleeding in this situation is to apply pressure by pinching the anterior portion of the nose for five to ten minutes. This is a common first aid technique used to stop nosebleeds, known as epistaxis. Applying pressure helps promote clotting and stops the bleeding. Placing the patient in a sitting position with the neck hyperextended or packing the nostrils with gauze for several days are not recommended first-line actions for controlling a nosebleed. The use of ice compresses to the forehead and neck may constrict blood vessels but is not as effective as direct pressure to the nose in this case.
Scoliosis That Greater 40 Degree Curvature Is Usually Treated By :
- A. Exercise
- B. Spinal fusion surgery
- C. Bracing
- D. Casting
Correct Answer: B
Rationale: When scoliosis progresses to a greater than 40-degree curvature, it is often treated with spinal fusion surgery. This surgical procedure involves fusing together the vertebrae in the curved part of the spine to correct the curvature. Spinal fusion surgery is typically recommended for severe cases of scoliosis to halt the progression of the curve and prevent further complications such as lung and heart problems. Other treatment options like exercise, bracing, and casting may be more suitable for milder cases or as a preventative measure in certain situations.
The nurse is taking care of a 7-year-old child with a skin rash called a papule. Which clinical finding should the nurse expect to assess with this type of skin rash?
- A. A lesion that is elevated, palpable, firm, and circumscribed; less than 1 cm in diameter
- B. A lesion that is elevated, flat-topped, firm, rough, and superficial; greater than 1 cm in diameter
- C. An elevated lesion, firm, circumscribed, palpable; 1 to 2 cm in diameter
- D. An elevated lesion, circumscribed, filled with serous fluid; less than 1 cm in diameter
Correct Answer: A
Rationale: A papule is a small, solid, elevated skin lesion that is less than 1 cm in diameter. It is usually palpable, firm, circumscribed, and can be various colors. Papules do not contain any fluid or pus. In this case, the nurse should expect to assess an elevated lesion that is firm and circumscribed, measuring less than 1 cm in diameter. This description matches option A, making it the correct choice for a papule.
