Correct Answer: A

Rationale: The correct answer is A: Irregular pulse. An irregular pulse may indicate an arrhythmia, which could be exacerbated by atenolol, a beta-blocker used to treat angina pectoris. Atenolol works by slowing the heart rate, so if the patient already has an irregular pulse, it could worsen with the medication. Tachycardia (choice B) would actually be an expected finding in a patient with angina pectoris, and atenolol is used to help reduce the heart rate in such cases. Chest pain (choice C) is a symptom that atenolol is meant to alleviate, so it would not be a reason to withhold the medication. Urinary frequency (choice D) is not directly related to the administration of atenolol for angina pectoris and would not require immediate reporting to the healthcare provider.

Correct Answer: C

Rationale: In a client with right-sided heart failure, crackles in the lungs are the most concerning finding as they indicate pulmonary congestion, which requires immediate intervention. Crackles suggest fluid accumulation in the lungs, leading to impaired gas exchange and potential respiratory distress. Jugular venous distention (Choice A) and peripheral edema (Choice B) are common findings in right-sided heart failure but do not indicate acute deterioration requiring immediate intervention. Elevated liver enzymes (Choice D) may be seen in chronic heart failure but do not warrant immediate action compared to the urgent need to address pulmonary congestion indicated by crackles in the lungs.

Correct Answer: C

Rationale: The client with viral meningitis and a temperature change is the most stable and appropriate for assignment to the PN. A change in temperature from 101°F to 102°F is not as critical as changes in Glasgow Coma Scale score, blood pressure, or wider blood pressure variations. The other clients require more complex monitoring and intervention due to their critical changes in status.

Correct Answer: C

Rationale: In a client with chronic heart failure receiving furosemide, crackles in the lungs indicate pulmonary congestion, requiring immediate intervention. This finding suggests fluid accumulation in the lungs, impairing oxygen exchange and potentially leading to respiratory distress. Monitoring and managing pulmonary congestion promptly are crucial to prevent worsening heart failure and respiratory compromise. The other options, while important to assess in a client with heart failure, do not indicate an immediate need for intervention like crackles in the lungs do. A heart rate of 60 beats per minute may be within the normal range for some individuals, a blood pressure of 110/70 mmHg is relatively stable, and peripheral edema is a common manifestation of heart failure that should be monitored but does not require immediate intervention compared to pulmonary congestion.

Correct Answer: B

Rationale: To calculate the volume to be administered for 35 mg of ceftazidime, divide the prescribed dose by the concentration: 35 mg / 100 mg/ml = 0.35 ml. Rounding off, the nurse should administer 0.4 ml for each dose. Choice A is incorrect as it doesn't consider rounding off. Choice C is incorrect because it's not the correct calculation. Choice D is incorrect as it doesn't reflect the accurate volume needed.
