1. A patient asks a nurse, “My doctor recommended I increase my intake of folic acid. What type of foods contain the highest concentration of folic acid?'
- A. Green vegetables and liver
- B. Yellow vegetables and red meat
- C. Carrots
- D. Milk
Correct answer: Green vegetables and liver
Rationale: Green vegetables and liver are rich sources of folic acid. Green vegetables like spinach, asparagus, and broccoli are high in folic acid content. Liver, especially from chicken or beef, is also a good source of folic acid. Yellow vegetables and red meat (choice B) do not contain as high a concentration of folic acid as green vegetables and liver. Carrots (choice C) are nutritious but do not have the highest concentration of folic acid. Milk (choice D) is not a significant source of folic acid compared to green vegetables and liver.
2. When printing out an EKG, a nurse notices that the QRS complexes are extremely small. What should be the next step?
- A. Alert the physician immediately as this is a sign of impending cardiac arrest.
- B. Check to see that all leads are attached and rerun the EKG.
- C. Increase the sensitivity control to 20 mm deflection.
- D. Decrease the run speed to 50.
Correct answer: Increase the sensitivity control to 20 mm deflection.
Rationale: Increasing the sensitivity control to 20 mm deflection will double the sensitivity, allowing for better observation of the small QRS complexes. This step is crucial in obtaining a clearer EKG reading. Choice A is incorrect because small QRS complexes do not necessarily indicate impending cardiac arrest; it's more likely a technical issue. Choice B is not the first step to take when small QRS complexes are observed; it's important to adjust the settings first. Choice D is incorrect because decreasing the run speed to 50 is not the appropriate action for this situation; adjusting the sensitivity control is more relevant to improve the visualization of the complexes.
3. A man has been taking lisinopril for CHF. The patient is seen in the emergency room for persistent diarrhea. The nurse is concerned about which side effect of lisinopril?
- A. Vertigo
- B. Hypotension
- C. Palpitations
- D. Nagging, dry cough
Correct answer: Hypotension
Rationale: The correct answer is 'Hypotension.' Lisinopril, an ACE inhibitor commonly used for CHF, can cause hypotension as a side effect. Persistent diarrhea can lead to dehydration, increasing the risk of hypotension in this patient. Vertigo (choice A) is not a typical side effect of lisinopril. Palpitations (choice C) are not directly associated with lisinopril use. A nagging, dry cough (choice D) is a common side effect of ACE inhibitors like lisinopril, but in this case, the patient's presentation with persistent diarrhea would make hypotension a more immediate concern.
4. A writer is admitted for the second time accompanied by his wife. He is demanding, arrogant, talks fast, and is hyperactive. Initially, the nurse should plan this for a manic client:
- A. Set realistic limits to the client’s behavior
- B. Repeat verbal instructions as often as needed
- C. Allow the client to express feelings to relieve tension
- D. Assign a staff member to be with the client at all times to help maintain control
Correct answer: Set realistic limits to the client’s behavior
Rationale: For a manic client who is demanding, arrogant, talks fast, and is hyperactive, setting realistic limits to the client’s behavior is essential to ensure safety as manic clients may engage in injurious activities. A quiet environment and consistent, firm limits help to maintain control. While repeating verbal instructions may be necessary due to distractibility, it is not the priority compared to setting limits for safety. Allowing the client to express feelings is important, but only non-destructive methods of expression should be permitted. Assigning a staff member to be with the client at all times is not a realistic approach as it may not always be feasible or necessary for managing manic behavior effectively.
5. Which of the following diseases would require the nurse to wear an N95 respirator as part of personal protective equipment?
- A. Human immunodeficiency virus
- B. Clostridium difficile enterocolitis
- C. Vancomycin-resistant enterococcus
- D. Measles
Correct answer: D: Measles
Rationale: Infections that require airborne precautions necessitate the use of an N95 respirator, a type of mask that filters particles that are 5 micrograms or smaller. Illnesses that require airborne precautions include Measles, Varicella, Severe Acute Respiratory Syndrome (SARS), and tuberculosis. Measles is a highly contagious airborne disease caused by a virus. It can spread through respiratory droplets when an infected person coughs or sneezes. Wearing an N95 respirator helps prevent the nurse from inhaling these infectious particles. Human immunodeficiency virus, Clostridium difficile enterocolitis, and Vancomycin-resistant enterococcus do not require the use of an N95 respirator as they are not transmitted through the air but have other modes of transmission.
