1. The nurse is preparing to administer the first dose of an antibiotic to a patient admitted for a urinary tract infection. Which action is most important prior to administering the antibiotic?
- A. Administering a small test dose to determine if hypersensitivity exists
- B. Having epinephrine available in case of a severe hypersensitivity reaction
- C. Monitoring baseline vital signs, including temperature and blood pressure
- D. Obtaining a specimen for culture and sensitivity
Correct answer: D
Rationale: The most crucial action before administering an antibiotic for a urinary tract infection is to obtain a specimen for culture and sensitivity. This ensures the accurate identification of the causative organism and helps determine the most effective antibiotic therapy. Administering a test dose to detect hypersensitivity is usually reserved for cases with a strong suspicion of allergy to a needed antibiotic. Keeping epinephrine available is important when there is a significant risk of a severe allergic reaction. Monitoring baseline vital signs is essential during antibiotic therapy but is not the top priority before administering the first dose.
2. The nurse instructs the unlicensed nursing personnel (UAP) on how to provide oral hygiene for clients who cannot perform this task for themselves. Which of the following techniques should the nurse tell the UAP to incorporate into the client's daily care?
- A. Assess the oral cavity each time mouth care is given and record observations.
- B. Use a soft toothbrush to brush the client's teeth after each meal.
- C. Swab the client's tongue, gums, and lips with a soft foam applicator every 2 hours.
- D. Rinse the client's mouth with mouthwash several times a day.
Correct answer: B
Rationale: The correct technique to incorporate into the client's daily care for oral hygiene is to use a soft toothbrush to brush the client's teeth after each meal. This helps in maintaining oral hygiene for clients who cannot perform this task themselves. Choice A is incorrect because assessing the oral cavity each time mouth care is given is important but not the technique to incorporate into daily care. Choice C is incorrect as swabbing the tongue, gums, and lips every 2 hours may not be necessary for daily care. Choice D is incorrect as rinsing the client's mouth with mouthwash several times a day may not be suitable for all clients and is not a standard recommendation for daily oral care.
3. A patient presents with severe chest pain radiating to the left arm. Which of the following diagnostic tests is the priority?
- A. Complete blood count (CBC)
- B. Electrocardiogram (ECG)
- C. Chest X-ray
- D. Serum electrolytes
Correct answer: B
Rationale: In a patient presenting with severe chest pain radiating to the left arm, the priority diagnostic test is an Electrocardiogram (ECG) to assess for myocardial infarction. An ECG can quickly identify changes indicative of ischemia or infarction, guiding prompt management. A Complete Blood Count (CBC) may provide some information but is not the primary test for evaluating chest pain related to myocardial infarction. A Chest X-ray can be useful in assessing lung pathologies or certain cardiac conditions; however, it does not provide immediate information on myocardial infarction, making it a secondary option in this scenario. Serum electrolytes may become important in later stages but do not offer immediate insights into myocardial infarction. Therefore, they are a lower priority compared to obtaining an ECG for timely diagnosis and intervention.
4. Which client is at greatest risk for coronary artery disease?
- A. A 32-year-old female with mitral valve prolapse who quit smoking 10 years ago.
- B. A 43-year-old male with a family history of CAD and a cholesterol level of 158 (8.8 mmol/L).
- C. A 56-year-old male with an HDL of 60 (3.3 mmol/L) who takes atorvastatin.
- D. A 65-year-old female who is obese with an LDL of 188 (10.4 mmol/L).
Correct answer: D
Rationale: The 65-year-old female who is obese with a high LDL level of 188 (10.4 mmol/L) is at the greatest risk for coronary artery disease. Obesity and high LDL cholesterol levels are significant risk factors for developing coronary artery disease. While factors like mitral valve prolapse (choice A) and a family history of CAD (choice B) can contribute to the risk, they are not as significant as obesity and high LDL levels. Choice C, a 56-year-old male with high HDL and taking atorvastatin, is actually at lower risk due to the high HDL levels and being on statin therapy, which helps reduce cholesterol levels and lower the risk of coronary artery disease.
5. A nurse cares for a client with diabetes mellitus who is prescribed metformin (Glucophage) and is scheduled for an intravenous urography. Which action should the nurse take first?
- A. Contact the provider and recommend discontinuing the metformin.
- B. Keep the client NPO for at least 6 hours prior to the examination.
- C. Check the client’s capillary artery blood glucose and administer prescribed insulin.
- D. Administer intravenous fluids to dilute and increase the excretion of dye.
Correct answer: A
Rationale: Metformin can cause lactic acidosis and renal impairment as the result of an interaction with the dye. This drug must be discontinued for 48 hours before the procedure and not started again after the procedure until urine output is well established. The client’s health care provider needs to provide alternative therapy for the client until the metformin can be resumed. Keeping the client NPO, checking the client’s blood glucose, and administering intravenous fluids should be part of the client’s plan of care, but are not the priority, as the examination should not occur while the client is still taking metformin.
