1. During a petit mal seizure in the clinic, what should be the highest priority?
- A. Provide a safe environment free of obstructions in the immediate area
- B. Call a code
- C. Contact the patient's physician
- D. Prevent excessive movement of the extremities
Correct answer: A
Rationale: During a petit mal seizure, the highest priority is to provide a safe environment free of obstructions in the immediate area. This action aims to prevent injuries to the patient during the seizure. While calling a code or contacting the patient's physician may be necessary at some point, immediate safety measures take precedence. Preventing excessive movement of the extremities is relevant but ensuring a safe environment is crucial to avoid harm during the seizure.
2. A client goes to the Emergency Department with acute respiratory distress and the following arterial blood gases (ABGs): pH 7.35, PCO2 40 mmHg, PO2 63mmHg, HCO3 23, and oxygenation saturation (SAO2) 93%. Which of the following represents the best analysis of the etiology of these ABGs?
- A. tuberculosis (TB)
- B. pneumonia
- C. pleural effusion
- D. hypoxia
Correct answer: D
Rationale: A combined low PO2 and low SAO2 indicates hypoxia. The pH, PCO2, and HCO3 are normal. ABGs are not necessarily altered in TB or pleural effusion. In pneumonia, the PO2 and PCO2 might be low because hypoxia stimulates hyperventilation, but the best analysis in this case is hypoxia due to the combination of low PO2 and low SAO2.
3. A client needs to rapidly achieve a therapeutic plasma drug concentration of a medication. Rather than wait for steady state to be achieved, the physician might order:
- A. a maintenance dose.
- B. a loading dose.
- C. a medication with no first-pass effect.
- D. the medication to be given intravenously.
Correct answer: B
Rationale: To rapidly achieve a therapeutic plasma drug concentration, a loading or priming dose is ordered. This dose quickly establishes the desired drug level. It is calculated by multiplying the volume of distribution by the desired plasma drug concentration. A maintenance dose, like choice A, is used to maintain the therapeutic level after the loading dose. Waiting for steady state without a loading dose would take five drug half-lives. Choice C, a medication with no first-pass effect, does not directly address the need for rapid attainment of therapeutic levels. While intravenous administration (choice D) offers excellent bioavailability, a single dose by this route may not achieve the desired therapeutic plasma concentration as rapidly as a loading dose.
4. While undergoing hemodialysis, the client becomes restless and tells the nurse he has a headache and feels nauseous. Which of the following complications does the nurse suspect?
- A. Infection.
- B. Disequilibrium syndrome.
- C. Air embolus.
- D. Infection.
Correct answer: C
Rationale: In this scenario, the client undergoing hemodialysis is experiencing symptoms like restlessness, a headache, and nausea. These symptoms are indicative of an air embolus, a serious complication that can occur during hemodialysis. Air embolus happens when air enters the bloodstream and can lead to symptoms like restlessness, a headache, and nausea. It is crucial for the nurse to suspect and address this complication promptly to prevent further harm to the client. Choices A and D (Infection) are less likely in this case, as the symptoms presented are more suggestive of an air embolus rather than an infection. Choice B (Disequilibrium syndrome) is also less likely as the symptoms described are not typical of this syndrome. Therefore, the correct answer is C: Air embolus.
5. A central venous pressure reading of 11cm/H(2)O of an IV of normal saline is determined by the nurse caring for the patient. The patient has a diagnosis of pericarditis. Which of the following is the most applicable?
- A. The patient has a condition of hypovolemia.
- B. Not enough fluid has been given to the patient.
- C. Pericarditis may cause pressures greater than 10cm/H(2)O with testing of CVP.
- D. The patient may have a condition of arteriosclerosis.
Correct answer: C
Rationale: A central venous pressure reading above 10cm/H(2)O may indicate a condition of pericarditis, as the inflammation and fluid accumulation around the heart can lead to elevated pressures. Choices A, B, and D are incorrect. Hypovolemia would typically result in lower CVP readings, not higher. Not enough fluid given would also lead to lower CVP levels. Arteriosclerosis is not directly related to CVP readings in the context of pericarditis.
