In assessing cardiovascular clients with progression of aortic stenosis, the nurse should be aware that there is typically:
- A. Decreased pulmonary blood flow and cyanosis
- B. Increased pressure in the pulmonary veins and pulmonary edema
- C. Systemic venous engorgement
- D. Increased left ventricular systolic pressures and hypertrophy
Correct Answer: D
Rationale: These signs are seen in pulmonic stenosis or in response to pulmonary congestion and edema and mitral stenosis. These signs are seen primarily in mitral stenosis or as a late sign in aortic stenosis after left ventricular failure. These signs are seen primarily in right-sided heart valve dysfunction. Left ventricular hypertrophy occurs to increase muscle mass and overcome the stenosis; left ventricular pressures increase as left ventricular volume increases owing to insufficient emptying.

A client with a history of hypertension is receiving Aldactone (spironolactone). The nurse should teach the client to avoid:
- A. Potassium-rich foods
- B. Calcium supplements
- C. High-fiber foods
- D. Iron supplements
Correct Answer: A
Rationale: Spironolactone is a potassium-sparing diuretic, and consuming potassium-rich foods can lead to hyperkalemia. Calcium, fiber, and iron supplements are not contraindicated.
Goal setting for a client with Meniere's disease should include which of the following?
- A. Frequent ambulation
- B. Prevention of a fall injury
- C. Consumption of three meals per day
- D. Prevention of infection
Correct Answer: B
Rationale: Although not contraindicated, initially ambulation may be difficult because of vertigo and is recommended only with assistance. Vertigo resulting in balance problems is one of the most common manifestations of Meniere's disease. Adequate nutrition is important, but the emphasis in Meniere's disease is not the number of meals per day but a decrease in intake of sodium. Infection is not an anticipated problem.
A mother frantically calls the emergency room (ER) asking what to do about her 3-year-old girl who was found eating pills out of a bottle in the medicine cabinet. The ER nurse tells the mother to:
- A. Give the child 15 mL of syrup of ipecac.
- B. Give the child 10 mL of syrup of ipecac with a sip of water.
- C. Give the child 1 cup of water to induce vomiting.
- D. Bring the child to the ER immediately.
Correct Answer: D
Rationale: Before giving any emetic, the substance ingested must be known. At least 8 oz of water should be administered along with ipecac syrup to increase volume in the stomach and facilitate vomiting. Water alone will not induce vomiting. An emetic is necessary to facilitate vomiting. Vomiting should never be induced in an unconscious client because of the risk of aspiration.
A client with a history of atrial flutter is admitted with complaints of dizziness. The nurse should give priority to:
- A. Monitoring heart rate
- B. Administering pain medication
- C. Monitoring respiratory rate
- D. Administering diuretics
Correct Answer: A
Rationale: Atrial flutter causes rapid heart rates, which can lead to dizziness due to reduced cardiac output, so monitoring heart rate is the priority.

- A. Scaly plaques
