NCLEX-RN Exam Questions - Part 46
1. A male client has been hospitalized with congestive heart failure. Medical management of heart failure focuses on improving myocardial contractility. This can be achieved by administering:
A) Digoxin (Lanoxin) 0.25 mg po every day
B) Furosemide (Lasix) 40 mg po every morning
C) O22 L/min via nasal cannula
D) Nitroglycerin (Nitrol) 1 inch topically every 4 hours
2. A clients congestive heart failure has been treated, and he will soon be discharged. Discharge teaching should include instruction to call the physician if he notices a 2-lb weight gain in a 24-hour period. Increased weight gain may indicate:
A) A diet too high in calories and saturated fat
B) Decreasing cardiac output
C) Decreasing renal function
D) Development of diabetes insipidus
3. A client was not using his seat belt when involved in a car accident. He fractured ribs 5, 6, and 7 on the left and developed a left pneumothorax. Assessment findings include:
A) Crackles and paradoxical chest wall movement
B) Decreased breath sounds on the left and chest pain with movement
C) Rhonchi and frothy sputum
D) Wheezing and dry cough
4. A client has a chest tube placed in his left pleural space to re-expand his collapsed lung. In a closed-chest drainage system, the purpose of the water seal is to:
A) Prevent air from entering the pleural space
B) Prevent fluid from entering the pleural space
C) Provide a means to measure chest drainage
D) Provide an indicator of respiratory effort
5. A client was admitted with rib fractures and a pneumothorax, which were sustained as a result of a motor vehicle accident. A chest tube was placed on the left side to reinflate his lung, and he was transferred to a client unit. Twenty-four hours after admission he continues to have bloody sputum, develops increasing hypoxemia, and his chest x-ray shows patchy infiltrates. The nurse analyzes these symptoms as being consistent with:
A) Pneumonia
B) Pulmonary contusions
C) Pulmonary edema
D) Tension pneumothorax
A) Digoxin (Lanoxin) 0.25 mg po every day
B) Furosemide (Lasix) 40 mg po every morning
C) O22 L/min via nasal cannula
D) Nitroglycerin (Nitrol) 1 inch topically every 4 hours

1. Right Answer: A
Explanation: (A) Digoxin is a cardiac glycoside given to clients in heart failure to improve their myocardial contractility. (B) Furosemide is a loop diuretic given to clients in heart failure to promote diuresis. (C) O2is given to clients in heart failure to increase oxygenation and to prevent or treat hypoxemia. (D) Nitroglycerin is a nitrate given to clients in heart failure to increase their cardiac output by decreasing the peripheral resistance that the left ventricle must pump against.
2. Right Answer: B
Explanation: (A) Increased calories may result in weight gain, but there is no indication in this question that this mans diet has changed in a way that would result in increased calories. (B) Decreasing cardiac output stimulates the renin-angiotensin-aldosterone cycle and results in fluid retention, which is reflected by weight gain. (C)Decreasing renal function may result in fluid retention, but this question gives no indication that this man has any renal problems. (D) Profound diuresis occurs with diabetes insipidus, which results in weight loss.
3. Right Answer: B
Explanation: (A) Crackles are caused by air moving through moisture in the small airways and occur with pulmonary edema. Paradoxical chest wall movement occurs with flail chest when a segment of the thorax moves outward on inspiration and inward on expiration. (B) Decreased breath sounds occur when a lung is collapsed or partially collapsed. Chest pain with movement occurs with rib fractures. (C) Rhonchi are caused by air moving through large fluid-filled airways. Frothy sputum may occur with pulmonary edema. (D) Wheezing is caused by fluid in large airways already narrowed by mucus or bronchospasm. Dry cough could indicate a cardiac problem.
4. Right Answer: A
Explanation: (A) A chest tube extends from the pleural space to a collection device. The tube is placed below the surface of the saline so that air cannot enter the pleural space. (B) Fluid may enter the pleural space as a result of injury or disease. A chest tube may drain fluid from the pleural space, but the water seal is not involved in this. (C) Chest drainage should be measured, but the water seal is not involved in this. (D) Fluctuations in the tube in the water-sealed bottle will give an indication of respiratory effort, but that is not the purpose of the water seal.
5. Right Answer: B
Explanation: (A) Pneumonia may be reflected by patchy infiltrates. In addition, fever, an increasing white blood cell count, and copious sputum production would be present. (B)Blunt chest traumacauses a bruising process in which interstitial and alveolar edema and hemorrhage occur. This is manifest by gradual deterioration over 24 hours of arterial blood gases and the continued production of bloody sputum. Patchy infiltrates are evident on chest xray 24 hours postinjury. (C) Pulmonary edema usually results from left heart failure. It is manifest by pink, frothy sputum; increasing dyspnea; tachycardia; and crackles on auscultation. (D) Tension pneumothorax is a potential complication for someone with rib fractures and a chest tube. It is manifest by diminished breath sounds on the affected side, rapidly deteriorating arterial blood gases in the presence of an open airway, and shock that is unexplained by other injuries.
