Early Goal Directed Therapy in severe sepsis and septic shock (Rivers et al) does NOT recommend:
- A. hydrocortisone 100 mg QID
- B. maintaining mixed venous oxygen saturation measurement >70%
- C. maintaining CVP between 8-12 mmHg
- D. using inotropes to keep MAP >65 mmHg<90 mmHg
Correct Answer: A
Rationale: Rivers' sepsis hydrocortisone's out, SvO2, CVP, MAP, dobutamine hold. Nurses skip this chronic steroid sidestep.

Which of the following statements is true related to nonmodifiable risk factors for chronic illness?
- A. Cannot be changed
- B. Requires intervention in order to change
- C. Can be altered to benefit health outcomes
- D. Can be changed with client perseverance
Correct Answer: A
Rationale: Nonmodifiable risk factors age, genes stay put, no tweak possible, a chronic base nurses work around. Intervention, alteration, or grit shift smoking or weight, not these locks. Knowing what's fixed guides focus elsewhere, a bedrock truth in illness planning.
Which is not an AIDS defining illness?
- A. oesophageal candidiasis
- B. Herpes Zoster
- C. CD4 count <200 cells/microL
- D. Pulmonary TB
Correct Answer: B
Rationale: Herpes zoster's no AIDS marker just shingles, common even sans HIV collapse. Oesophageal thrush, PCP, TB scream opportunists; CD4's a lab line, not illness. Nurses flag true definers chronic crash signs not this skin flare anyone catches.
The pathophysiology of Asthma differs from COPD as:
- A. It is characterised by airflow limitation
- B. There is abnormal inflammatory response to exposure to noxious particles or gases
- C. The airflow limitation is reversible
- D. It is considered an obstructive lung disease
Correct Answer: C
Rationale: Asthma's twist reversible airflow block sets it apart from COPD's fixed choke. Both obstruct, inflame to triggers, but asthma's airways bounce back with puffs. Nurses spot this, a chronic split for treatment.
A 50-year-old man diagnosed with leukemia will begin chemotherapy. What would the nurse do to combat the most common adverse effects of chemotherapy?
- A. Administer an antiemetic
- B. Administer an antimetabolite
- C. Administer a tumor antibiotic
- D. Administer an anticoagulant
Correct Answer: A
Rationale: Chemo's nastiest duo nausea and vomiting strike most patients, triggered by gut and brain reactions to drugs like cyclophosphamide. Antiemetics (e.g., ondansetron) preempt this, keeping patients eating and hydrated, a frontline move in oncology. Antimetabolites (like methotrexate) and tumor antibiotics (like doxorubicin) are chemo agents, not side-effect fixes. Anticoagulants dodge clots, not nausea. Nurses prioritize this relief, knowing it's the biggest hurdle to treatment tolerance.
A 60-year-old patient with a diagnosis of prostate cancer is scheduled to have an interstitial implant for high-dose radiation (HDR). What safety measure should the nurse include in this patient's subsequent plan of care?
- A. Limit the time that visitors spend at the patient's bedside
- B. Teach the patient to perform all aspects of basic care independently
- C. Assign male nurses to the patient's care whenever possible
- D. Situate the patient in a shared room with other patients receiving brachytherapy
Correct Answer: A
Rationale: HDR implants (brachytherapy) emit radiation limiting visitor time (e.g., 30 min) cuts exposure risk. Self-care's nice but not safety-driven. Gender's irrelevant pregnant staff avoid, not males. Shared rooms up exposure, not safety. Nurses in oncology enforce this, shielding others while the source's active, a radiation rule of thumb.
