Correct Answer: D

Rationale: The correct answer is to discontinue the IV infusion. Pain and swelling at the IV site may indicate infiltration or phlebitis, which requires immediate discontinuation of the infusion to prevent further complications. Continuing the infusion can lead to tissue damage or infection. Slowing the rate of infusion, applying a warm compress, or elevating the affected arm would not address the underlying issue of infiltration or phlebitis and could potentially worsen the condition by allowing more fluid to infiltrate the tissues.

Correct Answer: B

Rationale: Encouraging increased fluid intake is the most effective intervention in promoting airway clearance for a client with pneumonia. Increasing fluid intake helps to thin respiratory secretions, making it easier for the client to clear the airways. Administering bronchodilators may help with bronchospasm but does not directly promote airway clearance. Chest physiotherapy may be beneficial but is not the first-line intervention for promoting airway clearance in pneumonia. Providing humidified oxygen can improve oxygenation but does not directly address airway clearance.

Correct Answer: B

Rationale: The cervix functions in reproduction by secreting mucus that facilitates the transport of sperm to the uterus. Choice A is incorrect because the cervix does not interpret signals of sexual stimuli. Choice C is incorrect as the site for the union of ovum and sperm is the fallopian tube. Choice D is incorrect as the cervix is not involved in receiving the penis during intercourse.

Correct Answer: D

Rationale: When administering medication to children, it is crucial to ensure the correct dosage to prevent dosing errors. Double-checking the dosage calculations with another nurse can help verify the accuracy of the prescribed dose, reducing the risk of medication errors. While checking the child's weight (Choice A) is important for dosage calculation, it alone may not ensure the correctness of the dosage. Verifying the medication order with a pharmacist (Choice B) is essential, but it may not directly address the accuracy of dosage calculations. Consulting the child's parents (Choice C) is not a standard practice for verifying medication dosages and should not be solely relied upon for ensuring the correct dosage.

Correct Answer: A

Rationale: The correct answer is A: 'Decrease the dosage daily as prescribed.' Tapering the dosage of prednisone is crucial to prevent withdrawal symptoms and minimize the side effects of corticosteroid therapy. Decreasing the dosage gradually over time allows the body to adjust and reduces the risk of adrenal insufficiency. Choices B, C, and D are incorrect. Monitoring oral temperature daily, taking prednisone with meals, or returning for blood glucose monitoring in one week are not specific to the dosing schedule of prednisone for poison ivy treatment.
