1. Following mitral valve replacement surgery, a client develops PVCs. The healthcare provider orders a bolus of Lidocaine followed by a continuous Lidocaine infusion at a rate of 2 mg/minute. The IV solution contains 2 grams of Lidocaine in 500 mL of D5W. The infusion pump delivers 60 microdrops/mL. What rate would deliver 4 mg of Lidocaine per minute?
- A. 60 microdrops/minute
- B. 20 microdrops/minute
- C. 30 microdrops/minute
- D. 40 microdrops/minute
Correct answer: A
Rationale: To calculate the rate needed to deliver 4 mg/minute of Lidocaine, first, convert 2 grams to milligrams: 2 grams = 2000 mg. Then, set up a ratio between the total amount of Lidocaine (2000 mg) and the total volume of IV solution (500 mL): 2000 mg / 500 mL = 4 mg / x mL. Solving for x, x = 1 mL. Since the infusion pump delivers 60 microdrops per mL, multiplying by 60 microdrops/mL gives the correct rate of 60 microdrops/minute. This rate ensures the desired 4 mg of Lidocaine is delivered per minute. Choices B, C, and D are incorrect as they do not align with the accurate calculation based on the provided information.
2. While suctioning the endotracheal tube of an adult client, what level of pressure should the nurse apply?
- A. 70-80 mmHg
- B. 100-120 mmHg
- C. 150-170 mmHg
- D. 200 mmHg
Correct answer: B
Rationale: When suctioning the endotracheal tube of an adult client, the nurse should set the suction apparatus at a level no higher than 150 mmHg, with a preferable level between 100 and 120 mmHg. Suction pressure that is too high can contribute to the client's hypoxia. Alternatively, too low suction pressure may not clear adequate amounts of secretions. Choice A (70-80 mmHg) is too low and may not effectively clear secretions. Choices C (150-170 mmHg) and D (200 mmHg) are too high and can potentially harm the client by causing hypoxia or damaging the airway.
3. The nurse is caring for a woman 2 hours after a vaginal delivery. Documentation indicates that the membranes were ruptured for 36 hours prior to delivery. What are the priority nursing diagnoses at this time?
- A. Altered tissue perfusion
- B. Risk for fluid volume deficit
- C. High risk for hemorrhage
- D. Risk for infection
Correct answer: D
Rationale: The correct answer is 'Risk for infection.' When the membranes are ruptured for more than 24 hours prior to birth, there is a significantly increased risk of infection for both the mother and the newborn. Monitoring for signs of infection, such as fever, foul-smelling vaginal discharge, and uterine tenderness, is crucial. Option A, 'Altered tissue perfusion,' is not the priority in this scenario as infection risk takes precedence due to the prolonged rupture of membranes. Option B, 'Risk for fluid volume deficit,' is less of a priority compared to the immediate risk of infection. Option C, 'High risk for hemorrhage,' is not the priority concern at this time based on the information provided.
4. A patient diagnosed with alopecia would be described as having:
- A. body lice
- B. lack of ear lobes
- C. Indigestion
- D. hair loss
Correct answer: D
Rationale: The correct answer is 'hair loss.' Alopecia is a medical term that specifically refers to the condition of hair loss, usually in patches or all over the body. Choice A, 'body lice,' refers to a parasitic infestation and is not related to alopecia. Choice B, 'lack of ear lobes,' is completely unrelated to the term alopecia, which is solely about hair loss. Choice C, 'Indigestion,' has no connection to alopecia as it pertains to digestive issues, not hair loss. Therefore, the correct description for a patient diagnosed with alopecia is 'hair loss.'
5. A 25-year-old male client has been newly diagnosed with hypothyroidism and will take levothyroxine (Synthroid) 50 mcg/day by mouth. As part of the teaching plan, the nurse emphasizes that this medication:
- A. Should be taken in the morning
- B. May increase the client's energy level
- C. Does not need to be stored in a dark container
- D. May increase the client's heart rate
Correct answer: A
Rationale: The correct answer is that levothyroxine (Synthroid) should be taken in the morning. Taking it in the morning can help prevent interference with the client's sleeping pattern, as one of the side effects of levothyroxine is insomnia. Choice B is incorrect because levothyroxine is actually used to treat hypothyroidism and can help increase energy levels. Choice C is incorrect as there is no specific requirement for levothyroxine to be stored in a dark container. Choice D is incorrect because levothyroxine is more likely to increase heart rate rather than decrease it.
