Question 1 of 5
A client is prescribed with Pentamidine (Pentam) IV for the treatment of Pneumocystis carinii
Correct Answer: D
Rationale: A sudden increase in temperature (fever) to 101.5°F in a client receiving Pentamidine IV for Pneumocystis carinii pneumonia would most likely indicate the client has developed another infection. This is because Pentamidine IV is an antibiotic used to treat Pneumocystis carinii pneumonia, and a new fever during treatment would suggest a new or persistent infection causing the elevated temperature. It is important for the nurse to assess the client further and consider additional diagnostic tests or treatments for the new infection while continuing to monitor and manage the initial condition for which Pentamidine was prescribed.
Question 2 of 5
A 24-year-old sexually active woman presents to her primary care physician with vaginal itching and a greenish, frothy vaginal discharge. Her boyfriend is asymptomatic. She is prescribed metronidazole for Trichomonas vaginalis. Which of the following should be told to avoid while taking metronidazole?
Correct Answer: A
Rationale: Metronidazole treats Trichomonas vaginalis, and alcohol must be avoided. It inhibits aldehyde dehydrogenase, causing a disulfiram-like reaction (nausea, flushing). Aspirin , caffeine , grapefruit juice , and machinery (E) lack this interaction. This precaution prevents severe discomfort, ensuring treatment adherence.
Question 3 of 5
A 9-year-old boy is sent for neurologic evaluation because of episodes of apparent inattention. Over the past year, the child has experienced episodes during which he develops a blank look on his face and his eyes blink for 15 seconds. He immediately resumes his previous activity. Which one the following best describes this patient's seizures?
Correct Answer: D
Rationale: Absence seizures, typical in childhood, feature brief (10-20 second) lapses in awareness with staring and eye blinking, followed by immediate resumption of activity, as described. Simple partial seizures preserve consciousness with focal symptoms (e.g., twitching). Complex partial seizures impair awareness longer, with automatisms. Tonic-clonic seizures involve convulsions. Myoclonic seizures cause jerks without staring. The short duration, blank look, and rapid recovery align with absence seizures' EEG pattern (3 Hz spike-and-wave), distinguishing it here.
Question 4 of 5
the antidote for Warfarin is?
Correct Answer: B
Rationale: Warfarin is an oral anticoagulant that works by inhibiting the synthesis of vitamin K-dependent clotting factors in the liver. Therefore, the antidote for Warfarin overdose or to reverse its effects is vitamin K. Vitamin K helps in replenishing the depleted vitamin K-dependent clotting factors, allowing the blood to clot normally again. Administering vitamin K helps in reversing the anticoagulant effects of Warfarin, preventing excessive bleeding or hemorrhage.
Question 5 of 5
A client is prescribed clonidine (Catapres) for hypertension. Which statement by the client indicates effective teaching?
Correct Answer: C
Rationale: Clonidine, an alpha-2 agonist, lowers BP but risks rebound hypertension if stopped abruptly. Tapering off shows understanding, preventing this danger. Stopping if normal or extra doses risk instability. Chewing isn't advised'oral absorption suffices. Tapering aligns with clonidine's withdrawal risk, critical in hypertension management, making C the statement of effective teaching.
