1. The nurse is caring for a client with myasthenia gravis. Which symptom is most important for the nurse to report to the healthcare provider?
- A. Diplopia (double vision)
- B. Difficulty swallowing
- C. Weakness in the legs
- D. Fatigue
Correct answer: B
Rationale: In a client with myasthenia gravis, difficulty swallowing is the most crucial symptom to report to the healthcare provider. This is because it can lead to aspiration, a severe complication in these clients. Diplopia (double vision) and weakness in the legs are common symptoms of myasthenia gravis but are not as immediately dangerous as difficulty swallowing. Fatigue is also a common symptom in myasthenia gravis but does not pose the same risk of aspiration as difficulty swallowing.
2. The client with chronic venous insufficiency is being taught about self-care measures. Which instruction should be included?
- A. Avoid wearing compression stockings
- B. Elevate legs above heart level when resting
- C. Apply heat packs to improve circulation
- D. Limit walking to prevent leg pain
Correct answer: B
Rationale: The correct instruction for a client with chronic venous insufficiency is to elevate their legs above heart level when resting. This position helps reduce venous pressure and edema, improving circulation. Avoiding compression stockings (choice A) is incorrect as they are beneficial in managing chronic venous insufficiency. Applying heat packs (choice C) is not recommended as heat can worsen edema. Limiting walking (choice D) is not advisable as regular, gentle exercise like walking can actually help improve circulation in patients with chronic venous insufficiency.
3. What most influences the severity of respiratory distress syndrome (RDS)?
- A. Poor cough and gag reflex
- B. The gestational age at birth
- C. Administering high concentrations of oxygen
- D. The sex of the infant
Correct answer: B
Rationale: The correct answer is B. The gestational age at birth most influences the severity of respiratory distress syndrome (RDS). RDS is caused by a deficiency of surfactant and it occurs almost exclusively in preterm, low-birth weight infants. Therefore, the gestational age at birth is a key factor in determining the likelihood and severity of RDS. Choices A, C, and D are incorrect as they do not directly relate to the primary factor influencing the severity of RDS.
4. A client is receiving a secondary infusion of erythromycin 1 gram in 100 mL dextrose 5% in water (D5W) to be infused in 45 minutes. How many mL/hour should the nurse program the infusion pump?
- A. 100 mL/hour.
- B. 125 mL/hour.
- C. 133 mL/hour.
- D. 150 mL/hour.
Correct answer: C
Rationale: To infuse 100 mL in 45 minutes, the infusion rate should be set to 133 mL/hour (100 mL / 0.75 hours). This calculation is obtained by dividing the total volume to be infused by the total time for infusion (100 mL / 0.75 hours = 133 mL/hour). Therefore, choice C is the correct answer. Choices A, B, and D are incorrect because they do not accurately calculate the infusion rate required to deliver the medication within the specified time frame.
5. While changing the dressing of a client with a leg ulcer, the nurse observes a red, tender, and swollen wound at the site of the lesion. Before reporting this finding to the healthcare provider, the nurse should note which of the client’s laboratory values?
- A. Neutrophil count.
- B. Hematocrit.
- C. Blood pH.
- D. Serum potassium and sodium.
Correct answer: A
Rationale: The correct answer is A: Neutrophil count. Neutrophil count helps assess for infection, which is indicated by the redness, tenderness, and swelling of the wound. Elevated neutrophil count is a common sign of bacterial infection. Hematocrit (choice B) measures the proportion of blood volume that is occupied by red blood cells and is not directly related to wound infection. Blood pH (choice C) and serum potassium and sodium (choice D) are important for assessing acid-base balance and electrolyte levels but are not the primary indicators of wound infection.
