Rationale: The right to anonymity is the basic human right that exists when the subject's identity cannot be linked, even by the researcher, with his or her individual responses. Anonymity ensures that individuals can freely express their thoughts, opinions, and experiences without fear of being identified or facing any consequences. It is crucial in research to protect the privacy and confidentiality of participants, build trust, and encourage honest responses. Anonymity is a fundamental ethical principle in research to safeguard the rights and well-being of participants.

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.

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: B

Rationale: Assisting the client to a seated position on the toilet should be implemented first. This position promotes relaxation of the pelvic floor muscles and can help facilitate urinary elimination. It is a non-invasive and least intrusive intervention compared to performing intermittent catheterization or administering diuretic medication. Encouraging the client to drink plenty of fluids is important for promoting overall urinary function, but in this case, the priority is to aid the client in attempting to void first.

Correct Answer: B

Rationale: Goiter is a condition characterized by the enlargement of the thyroid gland. The most common cause of goiter worldwide is iodine deficiency, which is required for the production of thyroid hormones. When there is insufficient iodine intake, the thyroid gland enlarges in an attempt to produce more hormones, leading to the development of goiter. While other factors can also contribute to the development of goiter, such as autoimmune diseases and certain medications, the primary cause associated with the condition is an iodine-deficient diet.
