A nurse is caring for a client who has preeclampsia and is experiencing a postpartum hemorrhage. The nurse should expect the provider to prescribe which of the following medications?
Methylergonovine
Carboprost
Nifedipine
Oxytocin
The Correct Answer is D
A. Methylergonovine: While effective for postpartum hemorrhage, it causes vasoconstriction and can raise blood pressure significantly. It is contraindicated in clients with preeclampsia or hypertension due to the risk of stroke or hypertensive crisis.
B. Carboprost: Carboprost is used to treat postpartum hemorrhage, but it may increase blood pressure and is used cautiously in clients with preeclampsia. It is not typically the first-line treatment in hypertensive patients.
C. Nifedipine: Nifedipine is a calcium channel blocker used for managing hypertension and preterm labor, not for controlling postpartum bleeding. It does not cause uterine contraction and is not effective for hemorrhage.
D. Oxytocin: Oxytocin stimulates uterine contractions and is the first-line medication for managing postpartum hemorrhage. It does not raise blood pressure, making it safe and effective for clients with preeclampsia.

Correct Answer is B
Explanation
A. Atrial fibrillation: Atrial fibrillation is characterized by an irregularly irregular rhythm and the absence of identifiable P waves. It does not present with a consistent PR interval, making this an incorrect match for the findings.
B. First-degree atrioventricular block: This rhythm is defined by a consistently prolonged PR interval greater than 0.20 seconds with every P wave followed by a QRS complex. A PR interval of 0.35 seconds fits this definition, making this the correct answer.
C. Complete heart block: In third-degree or complete heart block, there is no relationship between P waves and QRS complexes—the atria and ventricles beat independently. The PR interval varies and is not constant.
D. Premature atrial complexes: These are early beats originating from the atria, often with a shortened or normal PR interval and an abnormal P wave. A consistently prolonged PR interval is not characteristic of PACs.
Correct Answer is C
Explanation
A. Have the client store smaller tanks under his bed: Storing oxygen tanks under the bed is unsafe due to limited ventilation and the potential for fire or physical damage. Oxygen tanks should be stored upright in well-ventilated areas, away from flammable materials.
B. Ensure that the client checks the gauge weekly: The oxygen gauge should be checked daily to ensure there is an adequate supply. Waiting a week between checks could lead to unexpectedly running out of oxygen, compromising the client's respiratory status.
C. Place the oxygen tank away from curtains or drapes: Curtains and drapes are flammable and can easily catch fire if oxygen leaks and an ignition source is nearby. Keeping oxygen tanks away from such materials helps reduce fire hazards in the home.
D. Store the oxygen tank wrench in a locked cabinet: The wrench should be stored nearby and easily accessible for emergency use or cylinder changes. Locking it away could delay a timely response if the tank needs adjustment.
