Question 1 of 5

An infant is diagnosed with patent ductus arteriosus. Which drug should the nurse anticipate administering to attempt to close the defect?

Correct Answer: D

Rationale: The correct answer is D: Indomethacin (Indocin). Indomethacin is a prostaglandin inhibitor that helps close the patent ductus arteriosus in infants by constricting the ductus arteriosus. This drug is specifically used for this purpose due to its mechanism of action. Digoxin (A) is a cardiac glycoside used for heart conditions, not to close PDA. Prednisone (B) is a corticosteroid that does not have a direct effect on closing PDA. Furosemide (C) is a diuretic used for managing fluid overload, not for closing PDA.

Question 2 of 5

Which of the following clients is most at risk for developing a deep-vein thrombosis?

Correct Answer: C

Rationale: The correct answer is C. A 40-year-old woman who smokes and uses oral contraceptives is at highest risk due to the combined effects of smoking and oral contraceptives, both of which increase the risk of blood clot formation. Smoking damages blood vessels and increases clotting tendency. Oral contraceptives also increase the risk of clotting due to hormonal changes. These factors can lead to the development of deep-vein thrombosis. Summary: A: 30-year-old postpartum client is at lower risk compared to smoking and oral contraceptive use. B: 63-year-old post-CVA on anticoagulant therapy is already being treated to prevent clots. D: 41-year-old female post-surgery is at lower risk compared to smoking and oral contraceptive use.

Question 3 of 5

A patient is admitted in acute distress with unrelieved back pain that radiates to his groin. This patient has a history of abdominal aortic aneurysm (AAA). What additional signs and symptoms might the patient state?

Correct Answer: B

Rationale: The correct answer is B: Bruit to left of the midline in the abdominal area. This is indicative of a possible ruptured AAA, as a bruit in the abdominal area can suggest turbulent blood flow due to an aneurysm. The other choices are incorrect because: A) Midsternal chest pressure relieved with nitroglycerin paste is more indicative of cardiac issues; C) Extreme headache is not typically associated with AAA; D) Numbness and tingling in the hands and arms are more suggestive of neurological issues rather than AAA. In summary, the presence of a bruit in the abdominal area is a key sign that should raise suspicion for a ruptured AAA in this patient.

Question 4 of 5

A patient has multiple saw-toothed P waves at a rate of 300 beats per minute. This patient's rhythm is most likely

Correct Answer: C

Rationale: The correct answer is C: Atrial flutter. A saw-toothed appearance of P waves at a rate of 300 bpm is characteristic of atrial flutter. In atrial flutter, the atria depolarize at a rapid rate, leading to a typical saw-tooth pattern on ECG. Paroxysmal atrial tachycardia (PAT) typically presents with sudden onset and termination of a regular tachycardia, not saw-toothed P waves. Premature atrial contractions (PACs) are early atrial depolarizations, not sustained at 300 bpm. Atrial fibrillation is characterized by irregularly irregular rhythm with no discernible P waves.
