Adult Health Nursing Study Guide Answers

Correct Answer: D

Rationale: Takotsubo cardiomyopathy, also known as stress-induced cardiomyopathy or broken heart syndrome, presents with symptoms similar to acute coronary syndrome, such as chest pain and ECG changes. In Takotsubo cardiomyopathy, chest pain typically occurs during emotional stress and resolves spontaneously, similar to the scenario described in the question. The ECG may show transient ST-segment elevation. This condition is characterized by a reversible left ventricular dysfunction that can mimic a myocardial infarction. Unlike stable angina (Choice A) and unstable angina (Choice B), Takotsubo cardiomyopathy is not related to coronary artery disease. Acute myocardial infarction (Choice C) typically presents with persistent ST-segment elevation on ECG and is caused by atherosclerotic plaque rupture leading to myocardial infarction, which is not consistent with the transient ST-segment elevation seen in

Correct Answer: A

Rationale: The described presentation of a pruritic, annular rash with central clearing and a raised, scaly border that spreads outward in a centrifugal pattern is characteristic of tinea corporis, commonly known as ringworm. This fungal infection affects the skin and is typically ring-shaped, with a well-defined, slightly raised, and scaly border. The central area often clears as the lesion enlarges peripherally, resembling a ring. It is important to note that ringworm is not caused by a worm but by a fungus. Treatment typically involves antifungal medications applied topically or taken orally, depending on the severity of the infection.

Correct Answer: B

Rationale: Patient's uterine contractions lasting 70 seconds and occurring every 90 seconds signify hyperstimulation, which can be a serious complication associated with oxytocin administration. This may result in decreased uterine perfusion, fetal distress, and other adverse effects. The first action should be to discontinue the oxytocin infusion to prevent further complications and allow the uterus to relax. Observations and assessment should continue to monitor the patient's condition and response after discontinuing the infusion. Giving an emergency bolus of oxytocin or increasing the IV infusion rate would exacerbate the hyperstimulation, and turning the client to her left side and breathing deeply would not address the underlying issue of oxytocin-induced hyperstimulation.

Correct Answer: D

Rationale: Cor pulmonale is a condition characterized by right heart failure secondary to pulmonary hypertension, which is often caused by chronic hypoxemia. Chronic hypoxemia occurs in conditions such as chronic obstructive pulmonary disease (COPD) where there is limited airflow in and out of the lungs, leading to low oxygen levels in the blood. However, the specific characteristic of pulmonary hypertension leading to right heart failure distinguishes cor pulmonale from COPD. Other conditions like idiopathic pulmonary fibrosis (IPF) and pulmonary embolism (PE) may also lead to hypoxemia but are not primarily associated with pulmonary hypertension and right heart failure as in cor pulmonale.

Correct Answer: D

Rationale: For a diagnostic pelvic ultrasound, one important preparation is to have the patient void or empty their bladder before the procedure. This allows for better visualization of the pelvic organs and structures during the ultrasound scan. A full bladder can obstruct the view and make it difficult to obtain accurate images. Therefore, it is essential for the patient to follow instructions to empty their bladder before the pelvic ultrasound to ensure the best results.
