1. A nurse is caring for an infant who has recently been diagnosed with a congenital heart defect. Which of the following clinical signs would most likely be present?
- A. Slow pulse rate
- B. Weight gain
- C. Decreased systolic pressure
- D. Irregular WBC lab values
Correct answer: B
Rationale: Weight gain due to fluid accumulation is associated with heart failure and congenital heart defects. When the heart is unable to circulate blood normally, the kidneys receive less blood, leading to reduced fluid filtration into the urine. The excess fluid accumulates in various body parts such as the lungs, liver, eyes, and sometimes in the legs. Slow pulse rate (Choice A) is less likely as infants with heart failure typically present with tachycardia due to the body compensating for decreased cardiac output. Decreased systolic pressure (Choice C) is also less likely as heart failure typically leads to increased blood pressure as the body tries to maintain adequate perfusion. Irregular white blood cell (WBC) values (Choice D) are not directly associated with congenital heart defects unless there is an underlying infection or inflammatory process.
2. After assessing Mr. B, what is the initial action of the nurse?
- A. Immediately place the client in a negative-pressure room
- B. Set the client up to receive a bronchoscopy
- C. Contact the physician for antifungal medications
- D. Administer oxygen and assist the client to sit in the semi-Fowler's position
Correct answer: A
Rationale: The first action the nurse should take after assessing Mr. B is to administer oxygen and assist him to sit in the semi-Fowler's position. Administering oxygen helps improve tissue oxygenation, while sitting up in a semi-Fowler's position aids in better breathing and secretion clearance. Placing the client in a negative-pressure room is not the immediate priority unless isolation is needed. Performing a bronchoscopy or contacting the physician for antifungal medications is not the initial step in managing a client with suspected pneumonia.
3. A patient is on bedrest 24 hours after a hip fracture. Which regular assessment or intervention is essential for detecting or preventing the complication of Fat Embolism Syndrome?
- A. Performing passive, light range-of-motion exercises on the hip as tolerated.
- B. Assess the patient's mental status for drowsiness or sleepiness.
- C. Assess the pedal pulse and capillary refill in the toes.
- D. Administer a stool softener as ordered.
Correct answer: B
Rationale: In detecting or preventing Fat Embolism Syndrome (FES), assessing the patient's mental status for drowsiness or sleepiness is crucial. Decreased level of consciousness is an early sign of FES due to decreased oxygen levels. Performing passive, light range-of-motion exercises on the hip may not directly relate to FES. Assessing pedal pulse and capillary refill in the toes is essential for assessing circulation but not specific to detecting FES. Administering a stool softener, while important for preventing constipation in immobilized patients, is not directly related to detecting or preventing FES.
4. A newborn has been diagnosed with hypothyroidism. In discussing the condition and treatment with the family, the nurse should emphasize:
- A. They can expect the child will be mentally retarded.
- B. Administration of thyroid hormone will prevent problems.
- C. This rare problem is always hereditary.
- D. Physical growth/development will be delayed.
Correct answer: B
Rationale: The correct answer is administration of thyroid hormone will prevent problems. In newborns diagnosed with hypothyroidism, early identification and continuous treatment with hormone replacement can correct this condition effectively. Choice A is incorrect as it uses outdated and inappropriate language (mentally retarded) and does not reflect modern understanding of conditions. Choice C is incorrect because while some cases of hypothyroidism can be hereditary, it is not always the case. Choice D is incorrect as physical growth and development can be affected by hypothyroidism, but the critical emphasis should be on the importance of administering thyroid hormone to prevent complications and support normal growth and development.
5. 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.
