Nokea
Which organism can not be detected by antigen testing of CSF, serum or urine?
- A. cryptococcus neoformans
- B. TB
- C. Ecoli
- D. Hemophilus
Correct Answer: B
Rationale: TB hides from antigen tests slow grower, no quick CSF, serum, or urine markers like cryptococcus' capsular catch, E. coli's bits, Haemophilus' caps, or Group B strep's flags. Nurses lean on culture or PCR here, a chronic stealth bug dodging rapid nets.

Damage control resuscitation:
- A. Is not indicated unless it is clear the patient's physiology has been deranged by severe injury.
- B. Is not indicated unless the patient is in the hospital.
- C. Is likely to involve restriction of fluid administration in a hypotensive, bleeding patient.
- D. Is likely is be assessed for adequacy by palpation of the radial pulse in patients with a head injury.
Correct Answer: C
Rationale: Damage control resuscitation (DCR) mitigates trauma's lethal triad (hypothermia, acidosis, coagulopathy). It's indicated preemptively in severe bleeding, not just post-derangement, to prevent physiologic collapse. It begins pre-hospital (e.g., paramedics), not only in-hospital, using blood products early. Fluid restriction in hypotensive bleeding limits dilutional coagulopathy, favoring permissive hypotension until haemostasis crucial in uncontrolled haemorrhage. Radial pulse palpation gauges perfusion broadly, but head injury patients need cerebral perfusion pressure prioritization, not DCR adequacy. ABC remains foundational. Fluid restriction's role balancing shock correction with bleeding exacerbation defines DCR's shift from crystalloid overload, improving survival in exsanguinating trauma.
Which drug regimen in AIDS is usually used?
- A. 2 nucleosides and nevirapine
- B. 2 nucleosides and a protease inhibitor
- C. 1 nucleoside, nevirapine and a protease inhibitor
- D. A and B
Correct Answer: D
Rationale: AIDS cocktails two nucleosides plus nevirapine or protease inhibitor, both slam HIV's lifecycle. Single's weak nurses mix these chronic viral brakes.
Insulin is an anabolic hormone. Question: A catabolic state induced by insulin deficiency has an effect on which metabolism?
- A. Protein metabolism
- B. Glucose metabolism
- C. Fat metabolism
- D. A+B+C
Correct Answer: D
Rationale: Insulin gone, catabolism rages proteins break, glucose spikes, fats burn all unravel. No picking one; it's a full-body crash nurses see this in type 1's ketosis, a chronic fuel flip.
A 50 year old man has a BP of 160/100 mmHg despite being on 10 mg Lisinopril om. Which of the following is not a good choice?
- A. Diuretic
- B. Calcium channel blocker
- C. Bisoprolol
- D. Losartan
Correct Answer: D
Rationale: BP 160/100 diuretic, calcium, beta, upping lisinopril stack; losartan doubles ACE, risks crash. Nurses dodge this chronic overlap.
A nurse is caring for a 19-year-old male recently diagnosed with leukemia. Which of the following nursing interventions is appropriate for the care of this client?
- A. Fluid restriction
- B. Low residual diet
- C. Therapeutic phlebotomy
- D. Strict hand hygiene to prevent infection
Correct Answer: D
Rationale: Leukemia's marrow mess drops immunity strict hand hygiene shields this 19-year-old from infections, a top intervention as neutrophils crash. Fluid restriction fits overload, not here. Low residual diets aid bowels, irrelevant. Phlebotomy's for polycythemia. Nurses scrub up, guarding this young client, a germ-free must in leukemia's fragile fight.
