Question 1 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 2 of 5
During an assessment of an older adult, the nurse should expect to notice which finding as a normal physiologic change associated with the aging process?
Correct Answer: C
Rationale: The correct answer is C. As individuals age, their peripheral blood vessels tend to become more rigid, leading to an increase in systolic blood pressure. This is a normal physiologic change associated with aging due to the loss of elasticity in the blood vessels. This change is commonly seen in older adults and is a result of the natural aging process. Choice A is incorrect because hormonal changes in older adults do not typically cause vasodilation leading to a drop in blood pressure. Choice B is incorrect as progressive atrophy of intramuscular calf veins is not a normal physiologic change associated with aging. Choice D is also incorrect as narrowing of the inferior vena cava does not typically occur as a normal part of the aging process, leading to low blood flow and varicosities.
Question 3 of 5
The nurse is describing a weak, thready pulse on the documentation flow sheet. Which statement is correct?
Correct Answer: C
Rationale: The correct answer is C because a weak, thready pulse is defined as being hard to palpate, may fade in and out, and can be easily obliterated by pressure. This indicates a pulse that is difficult to feel, lacks consistency, and may disappear with minimal pressure. Choice A is incorrect as a weak, thready pulse is not easily palpable and does not pound under the fingertips. Choice B is incorrect as it describes a pulse with greater than normal force that suddenly collapses, which is indicative of a bounding pulse, not a weak, thready pulse. Choice D is incorrect as it describes a pulse with varying force between beats, which is not characteristic of a weak, thready pulse.
Question 4 of 5
Mrs. Lenzo weighs herself every day with a very accurate balance-type scale. She has noticed that over the past 2 days she has gained 4 pounds. How would you best explain this?
Correct Answer: C
Rationale: The correct answer is C. Body fluid fluctuations can cause weight changes on a daily basis. Factors like water retention or dehydration can lead to temporary weight gain or loss. Mrs. Lenzo's 4-pound increase in 2 days is likely due to variations in body fluid levels rather than overeating, clothing, or instrument inaccuracy. It's important to consider physiological factors before jumping to conclusions.
Question 5 of 5
You are caring for a patient who was recently diagnosed with type 1 diabetes. She is learning to manage her diabetes and will need support after discharge. Her knowledge deficit is considered a _____ priority problem & will require a collaborative effort with health care professionals.
Correct Answer: B
Rationale: The correct answer is B: Second-level. In the nursing process, addressing a knowledge deficit for a patient with a new diagnosis like type 1 diabetes falls under second-level priority. This is because it is essential for the patient's immediate well-being and safety, but it does not pose a direct threat to their life or physiological stability. Collaborative effort with healthcare professionals is crucial to ensure the patient receives comprehensive education and support. Choice A: First-level priorities are for life-threatening issues requiring immediate attention, such as airway obstruction or cardiac arrest, which do not apply in this scenario. Choice C: Third-level priorities are important for long-term health outcomes but not immediate concerns like knowledge deficit in a newly diagnosed patient. Choice D: This option is likely incomplete and cannot be considered a valid choice.
