A nurse is caring for a client following the application of a cast. Which of the following actions should the nurse take first?

Correct Answer: B

Rationale: Palpating the pulse distal to the cast is the priority as it assesses for circulation. Ensuring adequate blood flow is essential to prevent complications such as compartment syndrome. Placing an ice pack over the cast could cause constriction of blood vessels, further compromising circulation. Teaching the client about cast care and positioning the casted extremity on a pillow are important but do not take precedence over assessing circulation.

Correct Answer: D

Rationale: The correct answer is D because contractions every 5 minutes that last 30 seconds indicate that the rate of infusion should be increased. This pattern suggests weak contractions or intervals that are too far apart, requiring an adjustment to improve labor progress. Option A is incorrect as a low urine output is not directly related to the need for an increase in the oxytocin infusion rate. Option B, Montevideo units consistently at 300 mm Hg, is incorrect because it is a measure of intrauterine pressure and does not determine the need for an increase in oxytocin infusion. Option C, FHR pattern with absent variability, is incorrect as it may indicate fetal distress but does not specifically relate to the need for adjusting the oxytocin infusion rate.

Correct Answer: C

Rationale: The correct answer is C. Spironolactone is a potassium-sparing diuretic, which means it helps the body retain potassium and excrete sodium and water. Therefore, clients on spironolactone should reduce their intake of foods high in potassium to prevent hyperkalemia. Choices A, B, and D are incorrect because limiting spinach intake due to warfarin, eating anchovies with gout, and taking calcium carbonate with water for osteoporosis do not directly relate to the medication's side effects or dietary restrictions associated with spironolactone.

Correct Answer: A

Rationale: In a client who is 30 minutes postoperative following an arterial thrombectomy, chest pain is a critical finding that should be reported immediately. Chest pain can indicate serious complications such as myocardial infarction or pulmonary embolism, which require prompt intervention. Muscle spasms and cool, moist skin are not typical signs of immediate concern following an arterial thrombectomy. Incisional pain is expected postoperatively and may not warrant immediate reporting unless accompanied by other concerning symptoms.

Correct Answer: C

Rationale: The correct answer is C: Penicillin allergy. Penicillin allergy is a contraindication for ceftriaxone because both medications are beta-lactam antibiotics. Seizure disorder (choice A), hypertension (choice B), and hyperlipidemia (choice D) are not contraindications for ceftriaxone and do not directly affect the use of this antibiotic.
