Nursing Elites

1. The nurse is teaching a client with asthma to use a peak expiratory flow rate (PEFR) meter to manage asthma at home. The nurse knows the client understands the proper use of the meter when the client:

• A. Inhales as rapidly as possible when using the meter
• B. Records the highest of three readings
• C. Uses the meter after taking a bronchodilator
• D. Blows out forcefully into the meter after taking a deep breath

Correct answer: B

Rationale: The correct answer is B: 'Records the highest of three readings.' When using a peak expiratory flow rate (PEFR) meter, the client should record the highest of three readings to ensure an accurate measurement of their peak expiratory flow rate. Inhaling rapidly, using the meter after taking a bronchodilator, or blowing out forcefully into the meter after a deep breath are not correct techniques for using a PEFR meter and may lead to inaccurate results.

2. The nurse prepares a discharge plan for an older adult client following cataract extraction. What instructions should the nurse provide?

• A. Avoid straining, bending, or lifting heavy objects.
• B. Limit exposure to sunlight for the first 2 weeks.
• C. Irrigate the conjunctiva with saline before applying ointment.
• D. Read without direct lighting for 6 weeks.

Correct answer: A

Rationale: The correct instruction for the nurse to provide after cataract extraction is to advise the client to avoid straining, bending, or lifting heavy objects. These activities can increase intraocular pressure, which should be minimized post-surgery to promote healing and prevent complications. Choices B, C, and D are incorrect because limiting sunlight exposure, irrigating the conjunctiva with saline, and reading without direct lighting are not primary instructions following cataract extraction.

3. A client with a tracheostomy develops copious, thick secretions. What is the nurse's priority action?

• A. Increase the client's fluid intake.
• B. Perform tracheal suctioning.
• C. Administer a mucolytic agent.
• D. Increase the humidity of the oxygen source.

Correct answer: D

Rationale: The correct answer is to increase the humidity of the oxygen source. This action helps thin thick secretions, making them easier to clear from the tracheostomy tube. Increasing fluid intake (Choice A) can be beneficial in some cases but addressing humidity is more specific to managing thick secretions in a client with a tracheostomy. Tracheal suctioning (Choice B) should be done after attempting to thin the secretions with increased humidity. Administering a mucolytic agent (Choice C) is a possible intervention but typically comes after addressing humidity and before resorting to suctioning to avoid unnecessary invasiveness.

4. A client with hyperthyroidism is admitted to the postoperative unit after a subtotal thyroidectomy. Which of the client's serum laboratory values requires intervention by the nurse?

• A. Blood glucose 90 mg/dL
• B. Sodium 138 mEq/L
• C. Total calcium 5.0 mg/dL
• D. Potassium 4.2 mEq/L

Correct answer: C

Rationale: A total calcium level of 5.0 mg/dL is critically low and indicates possible hypocalcemia, a common complication after thyroid surgery. This condition can lead to tetany and requires immediate intervention. Blood glucose within normal range, sodium, and potassium levels are not indicative of an immediate postoperative complication like hypocalcemia in this case.

5. Which of these findings would the nurse more closely associate with anemia in a 10-month-old infant?

• A. Hemoglobin level of 12 g/dL
• B. Pale mucosa of the eyelids and lips
• C. Hypoactivity
• D. A heart rate between 140 to 160

Correct answer: B

Rationale: The correct answer is B. Pale mucous membranes, such as those of the eyelids and lips, are a classic sign of anemia in infants. Anemia leads to decreased oxygen-carrying capacity, resulting in tissue hypoxia, which can manifest as pale mucosa. Choice A, a hemoglobin level of 12 g/dL, is within the normal range for a 10-month-old infant and would not necessarily indicate anemia. Choice C, hypoactivity, is a non-specific finding and can be present in various conditions, not specifically anemia. Choice D, a heart rate between 140 to 160, is within the normal range for an infant and is not a specific finding associated with anemia.
