Correct Answer: C

Rationale: Bone pain in the back of the ribs is a classic manifestation of multiple myeloma. Multiple myeloma is a type of cancer that primarily affects plasma cells in the bone marrow, leading to weakened bones and bone pain. Patients with multiple myeloma often experience bone pain in areas such as the ribs, spine, and pelvis. The bone pain is typically persistent and worsens with movement or pressure. Additionally, other common symptoms of multiple myeloma include anemia, kidney damage, recurrent infections, and elevated calcium levels in the blood.

Correct Answer: C

Rationale: Beta-adrenergic agonists stimulate beta-adrenergic receptors in the heart, leading to an increase in heart rate (tachycardia). This is a common adverse effect associated with the use of beta-adrenergic agonists in the management of conditions such as asthma. Monitoring for tachycardia is important because it can potentially lead to other complications such as palpitations, arrhythmias, and exacerbation of underlying cardiovascular conditions. It is essential for the nurse to closely monitor the patient for any signs or symptoms of tachycardia and report any abnormalities to the healthcare provider promptly to ensure appropriate management and prevent further complications.

Correct Answer: A

Rationale: The presentation of chest pain, dyspnea, hypotension, right ventricular dilation, and hypokinesis on echocardiogram is highly suggestive of a pulmonary embolism. In pulmonary embolism, a blood clot obstructs the pulmonary artery or one of its branches, leading to increased pressure in the right ventricle, which can cause right ventricular dilation and dysfunction. This results in the classic signs of right heart strain on echocardiogram. The patient may also present with symptoms of acute right heart failure, such as chest pain, dyspnea, and signs of hypotension. It is crucial to consider pulmonary embolism as a potential cause of these symptoms, given the high morbidity and mortality associated with this condition.

Correct Answer: B

Rationale: In assessing the health condition of school children, anemia and other blood disorders are more commonly observed in this age group compared to cancer, lice, parasites, fractures, and injuries. Anemia is a common health issue among children due to various factors such as poor nutrition, iron deficiency, and infections. Regular screening for anemia is important in school-age children to prevent long-term complications and to promote their overall health and well-being. While cancer, lice, parasites, fractures, and injuries can also occur in school children, anemia and blood disorders are more prevalent in this age group.

Correct Answer: D

Rationale: Fidelity is a principle in nursing ethics that pertains to being faithful or loyal to commitments and promises made to patients. When Nurse Pat promised to come back to assist in the patient's ambulation after carrying out the physician's order, she is demonstrating fidelity by fulfilling her commitment to the patient's care. This principle helps build trust between the nurse and the patient, ensuring continuity and quality of care.
