Drugs to be avoided in renal failure include:
- A. Allopurinol
- B. Digoxin
- C. Ceftazidime
- D. Acyclovir
Correct Answer: B

In which congenital heart defect (CHD) would the nurse need to take upper and lower extremity BPs?
- A. Transposition of the great vessels
- B. Aortic stenosis (AS)
- C. Coarctation of the aorta (COA)
- D. Tetralogy of Fallot (TOF)
Correct Answer: C
Rationale: COA causes increased blood pressure and strong pulses in the upper extremities with lower-than-expected BP and weak pulses in the lower extremities.
All the following conditions are associated with high volume pulse except
- A. Aorta to LV tunnel
- B. Coronary cameral fistula
- C. Neonatal Blalock Taussig shunt
- D. Hemitruncus
Correct Answer: C
Rationale: Neonatal Blalock Taussig shunt is not associated with a high volume pulse.
A nurse cares for a client who has advanced cardiac disease and states, I am having trouble sleeping at night. How should the nurse respond?
- A. I will consult the provider to prescribe a sleep study to determine the problem.
- B. You become hypoxic while sleeping; oxygen therapy via nasal cannula will help.
- C. A continuous positive airway pressure, or CPAP, breathing mask will help you breathe at night.
- D. Use pillows to elevate your head and chest while you are sleeping.
Correct Answer: D
Rationale: Elevating the head and chest can reduce fluid accumulation in the lungs, improving breathing and sleep quality in clients with advanced cardiac disease.
Hypothalamic nuclei are responsible for:
- A. Control of hunger
- B. Temperature control
- C. Maintaining osmolarity of extracellular fluid
- D. Secretion of thyrotrophin
Correct Answer: A
Rationale: The hypothalamus plays a key role in regulating hunger through various nuclei and hormonal signals.
What does the nurse explain that a ventricular septal defect will allow?
- A. Blood to shunt left to right, causing increased pulmonary flow and no cyanosis
- B. Blood to shunt right to left, causing decreased pulmonary flow and cyanosis
- C. No shunting because of high pressure in the left ventricle
- D. Increased pressure in the left atrium, impeding circulation of oxygenated blood in the circulating volume
Correct Answer: A
Rationale: Pulmonary blood flow is increased when a ventricular septal defect exists. The blood shifts from left to right because of the higher pressure in the left ventricle. This particular shift does not cause cyanosis.
