1. Which enzyme is most essential for the digestion of triglycerides found in butterfat?
- A. Gastric lipase
- B. Pepsin
- C. Mucus
- D. Intrinsic factor
Correct answer: A
Rationale: The correct answer is A: Gastric lipase. Gastric lipase is crucial for the digestion of short- and medium-chain triglycerides, such as those found in butterfat. Pepsin is involved in protein digestion, not lipid digestion. Mucus acts as a protective barrier in the stomach and does not play a direct role in lipid digestion. Intrinsic factor is involved in the absorption of vitamin B12 and is not related to the digestion of triglycerides.
2. What is the primary role of community health nurses in disaster preparedness?
- A. Developing emergency response plans
- B. Providing direct patient care
- C. Coordinating care among various providers
- D. Conducting health screenings
Correct answer: A
Rationale: Community health nurses primarily focus on developing emergency response plans in disaster preparedness. This involves creating strategies to address various aspects of a disaster, such as evacuation procedures, resource management, and communication plans. While providing direct patient care and coordinating care among providers are important aspects of nursing, in the context of disaster preparedness, the emphasis is on planning and preparedness to ensure an effective response in times of crisis.
3. A 55-year-old client has levothyroxine ordered. Which of the below past medical history concerns may contraindicate with her medication management of hypothyroidism?
- A. Scleroderma
- B. Osteoporosis
- C. Asthma
- D. Peripheral Vascular Disease
Correct answer: B
Rationale: The correct answer is B: Osteoporosis. Osteoporosis is a concern with levothyroxine as it can increase the risk for fractures, particularly in older adults. Levothyroxine treatment can exacerbate bone loss in individuals with osteoporosis. Choices A, C, and D are not directly contraindicated with levothyroxine therapy for hypothyroidism.
4. A client has been prescribed sertraline for depression, and the nurse is providing discharge instructions. Which dietary instruction should the nurse include?
- A. Avoid foods high in sodium.
- B. Avoid foods high in calcium.
- C. Avoid foods high in tyramine.
- D. Avoid foods high in potassium.
Correct answer: C
Rationale: Clients prescribed sertraline should avoid foods high in tyramine to prevent a hypertensive crisis. Sertraline, an antidepressant belonging to the selective serotonin reuptake inhibitor (SSRI) class, can interact with tyramine-rich foods, potentially causing a dangerous increase in blood pressure known as a hypertensive crisis. Choices A, B, and D are incorrect because there is no specific dietary restriction related to sodium, calcium, or potassium intake when taking sertraline.
5. Why are LDLs known as the 'bad' type of cholesterol?
- A. LDL (Low-Density Lipoprotein) is considered 'bad' cholesterol because it deposits cholesterol on the walls of arteries, leading to plaque formation and narrowing of the arteries (atherosclerosis).
- B. Both the statement and the reason are correct but are not related
- C. The statement is correct, but the reason is not correct
- D. The statement is not correct, but the reason is correct
Correct answer: A
Rationale: LDL (Low-Density Lipoprotein) is known as the 'bad' type of cholesterol because it deposits cholesterol on the walls of arteries, leading to plaque formation and narrowing of the arteries (atherosclerosis). This narrowing can restrict blood flow and increase the risk of serious cardiovascular conditions. The statement and the reason are directly related because the adherence of LDL to arterial walls and the subsequent narrowing of the lumen are the primary reasons why it is considered detrimental to heart health. Choice B is incorrect because the statement and reason are related. Choice C is incorrect because both the statement and the reason are correct. Choice D is incorrect because the statement correctly identifies LDL as the 'bad' type of cholesterol due to its actions in the arteries.
