Nursing Elites

1. Claudication is a well-known effect of peripheral vascular disease. Which of the following facts about claudication is correct? Select the one that doesn't apply:

• A. It results when oxygen demand is greater than oxygen supply.
• B. It is characterized by pain that often occurs during rest.
• C. It is a result of tissue hypoxia.
• D. It is characterized by cramping and weakness.

Correct answer: D

Rationale: Claudication is a symptom of peripheral vascular disease where there is an inadequate supply of oxygen to the muscles due to reduced blood flow. This mismatch between oxygen demand and supply leads to tissue hypoxia, resulting in cramping, weakness, and discomfort. Option D correctly states that claudication is characterized by cramping and weakness, making it the correct answer. Options A, B, and C are incorrect. Claudication occurs when oxygen demand exceeds supply, not the other way around as stated in Option A. Pain in claudication typically occurs with activity, not at rest as mentioned in Option B. While tissue hypoxia is a consequence of claudication, it is not the primary cause, making Option C incorrect.

2. A client is scheduled for a percutaneous transluminal coronary angioplasty (PTCA). The nurse knows that a PTCA is

• A. Surgical repair of a diseased coronary artery.
• B. Placement of an automatic internal cardiac defibrillator.
• C. Procedure that compresses plaque against the wall of the diseased coronary artery to improve blood flow.
• D. Non-invasive radiographic examination of the heart.

Correct answer: C

Rationale: Percutaneous transluminal coronary angioplasty (PTCA) is a procedure that involves compressing plaque against the wall of a diseased coronary artery to improve blood flow. It is a minimally invasive procedure performed during a cardiac catheterization to open blockages in the coronary arteries. Surgical repair of a diseased coronary artery refers to procedures like coronary artery bypass grafting (CABG), not PTCA. Placement of an automatic internal cardiac defibrillator is a different intervention used for managing cardiac arrhythmias, not for improving coronary blood flow. A non-invasive radiographic examination of the heart would typically refer to procedures like a cardiac CT scan or an MRI, not PTCA.

3. When assessing the respiratory system of an older patient, which finding indicates that the nurse should take immediate action?

• A. Weak cough effort
• B. Barrel-shaped chest
• C. Dry mucous membranes
• D. Bilateral crackles at lung bases

Correct answer: D

Rationale: Bilateral crackles at lung bases indicate a potential acute issue like heart failure. Immediate action is necessary in this situation. The nurse should conduct further assessments such as oxygen saturation and inform the healthcare provider promptly. A barrel-shaped chest and hyperresonance to percussion are typical signs of aging and do not require immediate action. A weak cough effort is common in older patients due to age-related changes, and dry mucous membranes are also expected in older individuals. While these findings may warrant further evaluation, they do not demand immediate action like bilateral crackles at lung bases.

4. A patient who has just been admitted with community-acquired pneumococcal pneumonia has a temperature of 101.6�F with a frequent cough and is complaining of severe pleuritic chest pain. Which prescribed medication should the nurse give first?

• A. Codeine
• B. Guaifenesin (Robitussin)
• C. Acetaminophen (Tylenol)
• D. Piperacillin/tazobactam (Zosyn)

Correct answer: D

Rationale: The correct answer is Piperacillin/tazobactam (Zosyn). Early initiation of antibiotic therapy is crucial in cases of community-acquired pneumococcal pneumonia to reduce mortality. While providing symptomatic relief with medications like Codeine for cough, Guaifenesin for mucus clearance, and Acetaminophen for fever and pain is important, the priority should be to start antibiotic therapy to target the underlying infection. Piperacillin/tazobactam is an appropriate choice for treating severe community-acquired pneumonia caused by pneumococcal organisms.

5. A healthcare provider calls a physician with the concern that a patient has developed a pulmonary embolism. Which of the following symptoms has the healthcare provider most likely observed?

• A. The patient is somnolent with decreased response to stimuli.
• B. The patient suddenly complains of chest pain and shortness of breath.
• C. The patient has developed a wet cough and the healthcare provider hears crackles on auscultation of the lungs.
• D. The patient has a fever, chills, and loss of appetite.

Correct answer: B

Rationale: The correct answer is 'The patient suddenly complains of chest pain and shortness of breath.' Typical symptoms of pulmonary embolism include chest pain, shortness of breath, and severe anxiety. The physician should be notified immediately. Clinical signs and symptoms for pulmonary embolism are nonspecific; therefore, patients suspected of having pulmonary embolism"?because of unexplained dyspnea, tachypnea, or chest pain or the presence of risk factors for pulmonary embolism"?must undergo diagnostic tests until the diagnosis is ascertained or eliminated or an alternative diagnosis is confirmed. Choices A, C, and D describe symptoms that are not typically associated with a pulmonary embolism, making them incorrect.
