Question 1 of 5
When assessing a patient's lungs, the nurse recalls that the left lung:
Correct Answer: A
Rationale: The correct answer is A: Consists of two lobes. The left lung indeed consists of two lobes - the upper lobe and the lower lobe, separated by the oblique fissure. The right lung, not the left lung, is divided by the horizontal fissure (B). The left lung primarily consists of the upper lobe on the anterior chest, not the posterior chest (C). The length of the lungs is not determined by the underlying organs like the stomach; it is mainly due to anatomical landmarks and structures. Therefore, option D is incorrect.
Question 2 of 5
In examining a 70-year-old male patient, the nurse notices that he has bilateral gynecomastia. Which of the following describes the nurse's best course of action?
Correct Answer: C
Rationale: The correct answer is C because gynecomastia in men is often caused by hormonal imbalances. By explaining this to the patient and recommending evaluation by a physician, the nurse ensures appropriate medical assessment and potential treatment. Choice A is incorrect because mammograms are not typically used to diagnose gynecomastia in men. Choice B is incorrect as gynecomastia should not be dismissed without further evaluation. Choice D is incorrect because gynecomastia is not always associated with prostate enlargement, and a thorough screening may not be necessary without more specific symptoms or risk factors.
Question 3 of 5
The sac that surrounds and protects the heart is called the:
Correct Answer: A
Rationale: The correct answer is A: Pericardium. The pericardium is the sac that surrounds and protects the heart. It consists of two layers - the outer fibrous pericardium and the inner serous pericardium. The fibrous pericardium provides structural support and protection, while the serous pericardium secretes fluid to reduce friction as the heart beats. Summary: B: Myocardium is the middle layer of the heart muscle responsible for pumping blood. C: Endocardium is the innermost layer of the heart lining the chambers and valves. D: Pleural space refers to the space between the lungs and the chest wall, not related to the heart.
Question 4 of 5
When listening to heart sounds, the nurse knows that the S1:
Correct Answer: C
Rationale: The correct answer is C because S1 coincides with the carotid artery pulse due to the closure of the atrioventricular valves (mitral and tricuspid). This occurs at the beginning of systole. A is incorrect as S1 is actually softer than S2 at the base of the heart. B is incorrect because S1 marks the beginning of systole, not diastole. D is incorrect as S1 is caused by the closure of the AV valves, not the semilunar valves.
Question 5 of 5
Jim is a 47-year-old man who is having difficulties with sexual function. He is recently separated from his wife of 20 years. He notes that he has early morning erections but otherwise cannot function. Which of the following is a likely cause for his problem?
Correct Answer: B
Rationale: The correct answer is B: Psychological issues. Jim's recent separation and inability to function sexually suggest a psychological cause, such as depression or anxiety. Early morning erections indicate physical capability, ruling out choices A, C, and D. Decreased testosterone levels (A) would not selectively affect sexual function, abnormal hypogastric arterial circulation (C) would lead to consistent erectile dysfunction, and impaired neural innervation (D) would affect all aspects of sexual function, not just specific situations. Therefore, psychological issues are the most likely cause for Jim's problem.
