Physical Examination and Health Assessment 8th Edition Test Bank

Correct Answer: D

Rationale: The scenario described with a strong pulse followed by a weak pulse is characteristic of pulsus paradoxus, a finding often associated with cardiac tamponade. Cardiac tamponade is a medical emergency where there is an accumulation of fluid (such as blood) in the pericardial sac that exerts pressure on the heart, limiting its ability to pump effectively. As a result, patients may exhibit this pulsus paradoxus, where the pulse strength varies with respiration. The other conditions listed (emphysema, asthma exacerbation, severe left heart failure) are not typically associated with this specific pulsatile pattern.

Correct Answer: C

Rationale: The target heart rate during physical activity is typically calculated as a percentage of maximum heart rate, which is estimated using the formula: 220 - age. For a 30-year-old individual, the estimated maximum heart rate would be 190 beats per minute. Exercising at 60-70% of the maximum heart rate is usually recommended for moderate-intensity physical activity. For this individual, the target heart rate zone would be approximately 114-133 beats per minute. Therefore, achieving a heart rate of 120 beats per minute would fall within the target range and indicate an appropriate level of exertion for effective physical activity.

Correct Answer: B

Rationale: Even after a unilateral mastectomy, women should continue to self-examine and have regular clinical examinations for any signs of recurrence or new masses. It is important to closely monitor the surgical scar area for any changes or abnormalities, as breast cancer can still occur in the remaining breast tissue. Regular breast examinations remain important in the early detection of any potential issues, even after mastectomy.

Correct Answer: C

Rationale: The information provided, specifically about the patient having three cesarean sections, is most appropriate to be placed under the Obstetrics/gynecology category. This category focuses on the healthcare of women, particularly during pregnancy, childbirth, and postpartum period, which includes details about cesarean sections. This information is not related to adult illnesses, surgeries in general, or psychiatric conditions.

Correct Answer: D

Rationale: The presence of a palpable pulsatile abdominal mass in a patient like Mr. Martin, who is a smoker and at risk for vascular diseases, is concerning for an abdominal aortic aneurysm (AAA). Immediate referral to a vascular surgeon is essential for further evaluation and management. AAA can be a life-threatening condition if left untreated, as it can lead to rupture and severe internal bleeding. Therefore, prompt specialist evaluation and monitoring are crucial in such cases. Waiting for 3 or 6 months for reevaluation could potentially lead to a delayed diagnosis and increase the risk of complications. Abdominal ultrasound is typically the diagnostic test of choice to confirm the presence and size of the aneurysm.
