A 3-year-old patient is taking therapeutic doses of Digoxin and Lasix for heart failure and has an order for daily labs to be drawn. What side effect of this drug combination would the nurse find most concerning?
- A. Hypernatremia
- B. Hypokalemia
- C. Hyponatremia
- D. Hyperkalemia
Correct Answer: B
Rationale: The correct answer is B: Hypokalemia. Digoxin and Lasix can both cause potassium loss, leading to hypokalemia. In this case, hypokalemia is concerning as it can increase the risk of Digoxin toxicity, resulting in life-threatening arrhythmias. Hypernatremia (A), hyponatremia (C), and hyperkalemia (D) are not common side effects of this drug combination and would not pose the same level of risk as hypokalemia.

A nurse is instructing a school-age child who has asthma about the use of a peak expiratory flow meter. Which of the following instructions should the nurse include?
- A. Place tongue on the mouthpiece of the meter.
- B. Maintain a semi-Fowler's position during testing.
- C. Record the average of the readings.
- D. Blow into the meter as hard and quickly as possible.
Correct Answer: D
Rationale: The correct answer is D: Blow into the meter as hard and quickly as possible. This instruction is correct because when using a peak expiratory flow meter, the individual needs to blow out as forcefully as possible to get an accurate reading of their peak expiratory flow rate. This helps in assessing the severity of asthma symptoms and monitoring the effectiveness of treatment.
A: Placing the tongue on the mouthpiece is incorrect as it may interfere with the airflow and affect the accuracy of the reading.
B: Maintaining a semi-Fowler's position is not necessary for using a peak flow meter.
C: Recording the average of the readings is not typically done with peak flow meters as the focus is on the individual's peak expiratory flow rate.
E, F, G: No other choices were provided.
In summary, blowing into the meter as hard and quickly as possible is the correct instruction for using a peak expiratory flow meter, as it ensures an accurate measurement of peak expir
Fentanyl 30mcg IV is ordered. The vial contains 0.05mg/ml. How many ml should the nurse administer?
- A. 0.3 ml
- B. 3 ml
- C. 0.06 ml
- D. 0.6 ml
Correct Answer: D
Rationale: To calculate the amount of Fentanyl to administer, first convert 30mcg to mg by dividing by 1000 (30mcg = 0.03mg). Then, divide the dose by the concentration of the vial (0.03mg ÷ 0.05mg/ml = 0.6ml). The correct answer is D (0.6ml). Choice A (0.3ml) is incorrect because it doesn't account for the correct dosage calculation. Choice B (3ml) is incorrect as it is too high, leading to potential overdose. Choice C (0.06ml) is incorrect as it miscalculates the dosage based on the vial concentration.
When assessing the child with atopic dermatitis, the nurse should ask the parents about a history of:
- A. Asthma
- B. Nephrosis
- C. Otitis media
- D. Neurotoxicity
Correct Answer: A
Rationale: The correct answer is A: Asthma. Atopic dermatitis is commonly associated with other allergic conditions, such as asthma. Asking about a history of asthma can help identify potential triggers and comorbidities. Nephrosis, otitis media, and neurotoxicity are not typically associated with atopic dermatitis, making choices B, C, and D incorrect. Always focus on relevant factors to provide effective care.
The nurse is caring for a school aged child in sickle cell crisis. Which interventions are appropriate for this patient? (Select all that apply)
- A. Application of a heating pad to the painful areas
- B. Start a Morphine PCA to provide pain relief for this patient
- C. Encourage patient to ambulate often to prevent pneumonia
- D. Hydrate patient with one-and-a-half-time maintenance fluid
Correct Answer: A,B,D
Rationale: Correct Answer: A, B, D
Rationale:
A: Application of a heating pad to the painful areas helps to relieve vaso-occlusive pain in sickle cell crisis by promoting vasodilation and increasing blood flow.
B: Starting a Morphine PCA is appropriate for pain management in sickle cell crisis as it provides controlled analgesia for the patient.
D: Hydrating the patient with one-and-a-half-time maintenance fluid helps prevent dehydration and maintain adequate blood flow, reducing the risk of vaso-occlusive episodes.
Incorrect Choices:
C: Encouraging the patient to ambulate often may not be suitable during a sickle cell crisis as it can increase the risk of pain and further complications.
E, F, G: No additional choices given, but typically options not directly related to pain management, hydration, or symptom relief would be incorrect in this scenario.
The nurse understands that the pathophysiology of a thermal injury includes (Select All that Apply):
- A. Hematuria
- B. Edema
- C. Hypovolemia
- D. Anemia
Correct Answer: B,C
Rationale: The correct answers are B: Edema and C: Hypovolemia. Edema occurs due to increased capillary permeability after a thermal injury, leading to fluid leakage into tissues. Hypovolemia results from fluid shift out of the blood vessels into the injured tissues, causing decreased blood volume. Hematuria (A) is not typically associated with thermal injuries. Anemia (D) is a decrease in the number of red blood cells or hemoglobin, not a direct result of thermal injury.
