After receiving change-of-shift report about these four clients, which client should the nurse assess first?

The 46-year-old with aortic stenosis who takes digoxin (Lanoxin) and has new-onset, frequent premature ventricular complexes Correct: This client's premature ventricular complexes may be indicative of digoxin toxicity. Further assessment for clinical manifestations of digoxin toxicity should be done and the physician notified about the dysrhythmia.

Which of these clients who have just arrived in the emergency department should the nurse classify as emergent and needing immediate medical evaluation?

The 70-year-old with a history of diabetes who has "tearing" back pain and is diaphoretic Correct: This client's history and clinical manifestations suggest possible aortic dissection and shock. The nurse will immediately assess the client's blood pressure and plan for IV antihypertensive therapy, rapid diagnostic testing, and possible transfer to surgery.

All of these client assignments have been made by the charge nurse. Which assignment would you question?

The LPN/LVN with 20 years of experience caring for a client with a headache whose blood pressure is 210/150 Correct: This client has unstable hypertension and is at risk for complications such as stroke, heart failure, or renal failure. The client should be assigned to an experienced RN, who can assess for end-organ damage and administer intravenous medications. A better assignment would be to assign Client D to an RN and Client C to the LPN/LVN.

Which of the following is essential to report to the provider when caring for a client with Raynaud's phenomenon?

The affected extremity becomes purple and cold. Correct: Cold, mottled extremities are indicative of occlusion, which could lead to gangrene.

All of this information is obtained by the nurse who is admitting a client for a coronary arteriogram. Which information is most important to report to the physician before the procedure begins?

The client develops wheezes and dyspnea after eating crab or lobster. Correct: The contrast agent injected into the coronary arteries during the arteriogram is iodine based. The client with a shellfish allergy is likely to have an allergic reaction to the contrast and should be medicated with an antihistamine or a steroid before the procedure.

The nurse is assigned to the following group of clients. Which of these clients should be assessed first?

The client who had percutaneous transluminal angioplasty of the right femoral artery 30 minutes ago Correct: This client should have checks of vascular status and vital signs every 15 minutes in the first hour after the procedure.

After receiving change-of-shift report in the coronary care unit, which client should you assess first?

The client with acute coronary syndrome who has a 3-pound weight gain and dyspnea Correct: Dyspnea and weight gain are symptoms of left ventricular failure and pulmonary edema; the client needs prompt intervention.

A client admitted for heart failure has a priority problem of Excess Fluid Volume related to compromised regulatory mechanisms. Which of these assessment data obtained the day after admission is the best indicator that the treatment has been effective?

The client's weight decreases by 2.5 kg. Correct: The best indicator of fluid volume loss is daily weight; because each kilogram represents approximately 1 L, this client has lost approximately 2500 mL of fluid.

The nurse encourages the client to increase his fluid intake after a cardiac catheterization for which reason?

The dye causes an osmotic diuresis. Correct: The dye is osmotically heavy, causing increased urine output, possible decreased blood flow to the kidney, and renal impairment.

Which nursing intervention for a client admitted today with heart failure will assist the client to conserve energy?

The nurse obtains a bedside commode before administering furosemide. Correct: Limiting the need for ambulation on the first day of admission to sitting in a chair or performing basic leg exercises promotes physical rest and reduced oxygen demand.

The client begins therapy with lisinopril (Prinivil, Zestril). What should the nurse consider at the start of therapy with this medication?

The risk for hypotension Correct: Angiotensin-converting enzyme (ACE) inhibitors are associated with first-dose hypotension and orthostatic hypotension, which are more likely in those older than 75 years.

Which assessment finding for a client with left ventricular failure who is receiving pulmonary artery pressure (PAP) monitoring indicates a need for rapid action by the nurse?

The waveform shows that the catheter is continuously in the wedge position. Correct: Because a pulmonary infarction can occur if the catheter is left in the wedged position, the nurse should have the client cough and/or should change the client's position. If the catheter remains wedged, the physician should be notified immediately.

Which statement best reflects correct client education for a client with a blood pressure (BP) of 134/86?

This blood pressure increases the workload of the heart; the client should consider modifying his or her lifestyle. Correct: Although not considered hypertension because the blood pressure is not greater than 140/90, it is consistent with increased risk for heart disease; the client requires further education.

The nurse is teaching a client about the purpose of electrophysiology studies (EPS). Which statement reflects the most correct teaching?

This test evaluates you for potentially fatal cardiac rhythms. Electrophysiology studies (EPS) are invasive tests performed to determine whether the client has lethal dysrhythmias.

The client has been admitted to the hospital with chest pain radiating down the left arm. The pain has been unrelieved by rest and antacids. Which test result best confirms that the client sustained a myocardial infarction?

Troponin of 5.2 ng/mL Correct: The presence of elevated troponin indicates myocardial damage; normal troponin should be less than 0.03 ng/mL.

The nurse caring for a client who has had AAA repair would be most alarmed by which finding?

Urine output of 20 mL over 2 hours Correct: Renal failure is a complication of AAA repair caused by blood loss or clips applied above to the aneurysm, which may interfere with renal artery perfusion.

The nurse teaches a client who has had a myocardial infarction (MI) which information regarding diet?

Use canola oil rather than palm or coconut oil. Correct: Palm and coconut oils are higher in saturated fats and are to be avoided.

The nurse is assessing a client with mitral stenosis who is to undergo a transesophageal echocardiogram (TEE) today. Which nursing action is essential?

Validate that the client has remained NPO. Correct: Owing to the risk for aspiration, the client must be NPO before the procedure.

Which teaching should the nurse include for a client with peripheral arterial disease (PAD)?

Walk to the point of leg pain, then rest, resuming when pain stops. Correct: Exercise may improve arterial blood flow by building collateral circulation; walk until the point of claudication, stop and rest, and then walk a little farther.

When following up in the clinic with a client with heart failure, how does the nurse recognize that the client has been compliant with fluid restrictions?

Weight loss of 6 pounds since the last visit Correct: Weight loss in this client indicates effective fluid restriction and diuretic drug therapy.

The nurse is educating a group of women about the differences in symptoms of MI in men versus those in women. Which information should be included?

Women may experience extreme fatigue and dizziness as sole symptoms. Correct: Women may have atypical symptoms, including absence of chest pain and extreme dizziness and fatigue.
