A nurse is caring for an infant who has a prescription for continuous pulse oximetry. Which of the following is an appropriate action for the nurse to take?

Correct Answer: B

Rationale: The correct answer is to move the probe site every 3 hours. This action helps prevent skin breakdown and ensures accurate readings. Placing the infant under a radiant warmer (Choice A) is not necessary for pulse oximetry monitoring. Heating the skin before placing the probe (Choice C) can potentially cause burns in infants. Placing a sensor on the index finger (Choice D) is not the standard practice for continuous pulse oximetry in infants.

Correct Answer: B

Rationale: An aPTT of 60 seconds indicates that the client is receiving an effective dose of heparin. The activated partial thromboplastin time (aPTT) measures the time it takes for blood to clot and is used to monitor heparin therapy. A therapeutic range for aPTT during heparin therapy is usually 1.5 to 2 times the control value, which is around 25-35 seconds. Platelets, hemoglobin, and INR values are not direct indicators of the effectiveness of heparin therapy.

Correct Answer: B

Rationale: Methimazole is the correct answer. It is commonly used to manage hyperthyroidism by inhibiting the production of thyroid hormones. Levothyroxine (Choice A) is actually a medication used to treat hypothyroidism by supplementing thyroid hormones. Propylthiouracil (Choice C) is another anti-thyroid medication used in the management of hyperthyroidism. Prednisone (Choice D) is a corticosteroid and is not typically used in the treatment of hyperthyroidism.

Correct Answer: A

Rationale: The correct answer is to administer bronchodilators. During an acute asthma attack, bronchodilators like albuterol are crucial to help dilate the airways and improve breathing. Providing supplemental oxygen (Choice B) may be necessary but is not the priority intervention. Starting IV fluids (Choice C) and monitoring oxygen saturation (Choice D) are important aspects of care but are not the most critical interventions during an acute asthma attack.

Correct Answer: D

Rationale: The correct answer is 'D: I will reduce my intake of processed meats.' This choice indicates an understanding of the teaching because processed meats are high in sodium, which can worsen heart failure due to fluid retention. Choices A, B, and C do not directly address the issue of reducing sodium intake, which is crucial for clients with heart failure. Increasing canned vegetable intake (A) may not always be advisable due to potential high sodium content in canned products. Limiting sodium intake to 2 grams daily (B) is a good practice, but it's more specific to sodium restriction rather than addressing the source of sodium like processed meats. Increasing whole grains (C) is generally beneficial but does not directly relate to reducing sodium intake in heart failure clients.

Correct Answer: B

Rationale: The correct answer is to move the probe site every 3 hours. This action helps prevent skin breakdown and ensures accurate readings. Placing the infant under a radiant warmer (Choice A) is not necessary for pulse oximetry monitoring. Heating the skin before placing the probe (Choice C) can potentially cause burns in infants. Placing a sensor on the index finger (Choice D) is not the standard practice for continuous pulse oximetry in infants.

Correct Answer: A

Rationale: The correct answer is to monitor BUN (Blood Urea Nitrogen) and creatinine levels in a patient with chronic kidney disease. These tests provide crucial information about renal function. Checking blood glucose levels (Choice B) is important for monitoring diabetes, not renal function. Monitoring hemoglobin and hematocrit levels (Choice C) helps assess anemia, not specifically renal function. Monitoring liver enzymes (Choice D) is relevant for assessing liver function, not renal function.

Correct Answer: B

Rationale: The correct answer is B because the client should exhale quickly and forcefully into the peak flow meter after taking a deep breath to measure peak expiratory flow. Choice A is incorrect as blowing as hard as possible may not provide an accurate reading. Choice C is incorrect because inhaling deeply before blowing can affect the results. Choice D is incorrect as holding the breath before exhaling is not part of using a peak flow meter.

Correct Answer: A

Rationale: Verifying the patient's identity is a critical step when administering a blood transfusion to ensure that the correct blood product is given to the right patient. This process helps prevent errors and enhances patient safety. Choice B, 'Administer medication,' is incorrect because the focus during a blood transfusion should be on ensuring the correct blood product is administered. Choice C, 'Monitor vital signs,' is also important but comes after verifying the patient's identity. Choice D, 'Start blood transfusion without verification,' is incorrect and unsafe as patient identification verification is essential prior to starting any medical procedure, especially one as important as a blood transfusion.
