Jarvis Physical Examination and Health Assessment Practice Questions

Correct Answer: C

Rationale: The presence of an irregular, asymmetric, hard nodule on the posterior surface of the prostate detected during digital rectal examination raises suspicion for prostate cancer. Prostate cancer commonly presents with nodules or indurations on the prostate gland during physical examination. Other findings, such as no inflammation, masses, or fissures in the anus and normal examinations of the scrotum and penis, further support the likelihood of prostate cancer as the most probable diagnosis in this case. Additional laboratory results, including prostate-specific antigen (PSA) levels, can help confirm the diagnosis. Both benign prostatic hyperplasia (BPH) and prostatitis typically present with different symptoms than those described in the scenario, making prostate cancer the most likely disorder based on the provided information. Anorectal cancer is less likely given the absence of findings indicating involvement of the anus or rectum in this case.

Correct Answer: A

Rationale: In a 30-year-old man with a firm, 2-cm mass under his areola and no other symptoms, the most likely diagnosis is breast tissue. Gynecomastia is a common condition in males where there is proliferation of breast tissue. It typically presents as a firm subareolar mass and can occur due to hormonal imbalances, medication use, or underlying medical conditions. Given the lack of family history of breast cancer, absence of other symptoms, and the age of the patient, breast tissue is the most probable diagnosis in this case. Breast cancer is less likely in this scenario, especially without any additional concerning findings or family history. Fibrocystic disease and lymph node involvement are also less likely given the presentation of a firm mass under the areola.

Correct Answer: A

Rationale: The most appropriate amount for a weekly weight reduction goal is typically .5 to 1 pound per week. This rate of weight loss is considered safe and sustainable in the long term. Losing weight too quickly (options B, C, D) can be harmful to your health and may lead to muscle loss, nutritional deficiencies, and a slow metabolism. Rapid weight loss is also harder to maintain in the long run. Gradual weight loss of .5 to 1 pound per week allows for healthy changes to diet and exercise habits, making it more likely to be maintained over time. It is also more likely to result in lasting weight loss and overall improvements in health and well-being.

Correct Answer: B

Rationale: The third heart sound (S3) is a low-frequency sound heard in early diastole, immediately following the second heart sound (S2). It is generated by the abrupt deceleration of the column of blood against the ventricular wall during the rapid passive filling phase (early diastole) when the ventricle is suddenly stretched by a large volume of blood. The S3 sound typically reflects decreased ventricular compliance, rather than normal compliance. An S3 sound is often considered pathological and is commonly associated with conditions such as heart failure, volume overload, and dilated cardiomyopathy. Therefore, the statement that the third heart sound reflects normal compliance of the left ventricle (Choice B) is incorrect.

Correct Answer: A

Rationale: The description provided fits the criteria for tension-type headache. Tension-type headaches are typically described as a mild to moderate, dull, band-like pressure or tightness around the head. They can last from minutes to days and are often triggered by stress, anxiety, poor posture, or prolonged computer use. The absence of symptoms like photophobia and nausea, along with the response to over-the-counter medication, further support the diagnosis of tension-type headache in this case. Other headache types such as migraines or cluster headaches usually present with additional symptoms like nausea, photophobia, or tearing of the eye, which are not mentioned in this scenario. Analgesic rebound headaches typically occur in individuals who overuse pain medications, leading to worsening headaches when the medication wears off, but this patient's history does not suggest such misuse.
