Correct Answer: A

Rationale: Sherry is a type of fortified wine produced in Spain. It is not associated with the development of hyperkalemia, which is a condition characterized by high levels of potassium in the blood. Hyperkalemia is commonly caused by kidney dysfunction, certain medications, or excessive intake of potassium-rich foods. Drinking Sherry is not likely to cause hyperkalemia. On the other hand, Sherry consumption can potentially contribute to tooth decay, gastric ulcers, and rectal bleeding due to its acidity and alcohol content.

Correct Answer: A

Rationale: Beta-blockers are medications commonly used in the management of heart failure. One of the therapeutic effects of beta-blockers is to decrease the heart rate. By blocking the action of adrenaline on the heart, beta-blockers help to slow down the heart rate, reduce the workload on the heart, and improve overall heart function. In patients with heart failure, a decreased heart rate is a favorable outcome as it can help improve cardiac output and reduce symptoms of heart failure such as fatigue and shortness of breath. Monitoring the heart rate is an important assessment parameter to evaluate the effectiveness of beta-blocker therapy in patients with heart failure. Therefore, a decreased heart rate would indicate a therapeutic effect of beta-blocker therapy in this patient.

Correct Answer: A

Rationale: The patient's presentation of episodic throbbing headache associated with nausea, vomiting, sensitivity to light and sound, and aura suggests a diagnosis of migraine headache. Migraines are a common neurological condition characterized by recurrent moderate to severe headaches that are often unilateral, pulsating, and aggravated by physical activity. The presence of premonitory symptoms (aura) before the headache is a key feature commonly seen in migraines. Additionally, nausea, vomiting, and sensitivity to light and sound are also common features associated with migraines.

Correct Answer: A

Rationale: When handling information about families in the community, the nurse should consider the principle of confidentiality as ethical. Confidentiality refers to the obligation of healthcare providers to safeguard the privacy of patient information. By maintaining confidentiality, the nurse upholds trust and respect in the nurse-family relationship. This principle ensures that sensitive information shared by families is kept secure and not disclosed without permission, thus respecting their autonomy and promoting open communication in healthcare settings.

Correct Answer: D

Rationale: Ovarian torsion is the most likely cause of the pregnant woman's symptoms as described. Ovarian torsion occurs when the ovary twists on its pedicle, leading to compromised blood flow to the ovary. This can cause severe abdominal pain, bloating, and constipation. On examination, an abdominal mass may be palpable due to an enlarged, twisted ovary. Bowel sounds may be diminished due to the effect of the torsion on surrounding structures. Ectopic pregnancy, threatened abortion, and placenta previa are less likely to present with an abdominal mass and diminished bowel sounds.
