In CSF of a patient with viral meningitis, the most prominent white cell is usually?
- A. monocytes
- B. lymphocytes
- C. polymorphs
- D. eosinophils
Correct Answer: B
Rationale: Viral meningitis pulls lymphocytes immune sentinels flood CSF, not polymorphs of bacterial wars, monocytes lagging, eosinophils for worms, or vague granulocytes. It's the chronic viral signature nurses spot this shift, ruling out pus-filled bacterial chaos with one cell peek.

A 56-year-old patient comes to the walk-in clinic for scant rectal bleeding and intermittent diarrhea and constipation for the past several months. There is a history of polyps and a family history for colorectal cancer. While you are trying to teach about colonoscopy, the patient becomes angry and threatens to leave. What is the priority diagnosis?
- A. Diarrhea/Constipation related to altered bowel patterns
- B. Knowledge Deficit related to disease process and diagnostic procedure
- C. Risk for Fluid Volume Deficit related to rectal bleeding and diarrhea
- D. Anxiety related to unknown outcomes and perceived threat to body integrity
Correct Answer: D
Rationale: The patient's anger and threat to leave during colonoscopy teaching signal emotional distress overriding physical symptoms. Anxiety stemming from uncertain outcomes and perceived bodily threat fits, as colorectal cancer risk tied to polyps and family history heightens fear, blocking education uptake. Diarrhea/constipation reflects symptoms but isn't immediately urgent with scant bleeding. Knowledge deficit exists but is secondary fear drives the refusal, not just ignorance. Fluid volume risk is plausible with bleeding, yet no data suggests acute loss; stability allows focus on emotions. Addressing anxiety first calms the patient, enabling teaching and care, a priority in this tense encounter where psychological barriers could delay critical colorectal screening and intervention.
Which of the following statements regarding weight regulation is FALSE?
- A. The reward system of weight regulation cannot override the signals from the homeostatic weight regulation circuitry
- B. Weight regain after weight loss is physiological and not necessarily due to a failure of conscious efforts to lose weight
- C. Liking and wanting of food are subconscious processes
- D. In human studies, functional MRI (fMRI) studies have shown overactivation of reward-encoding brain regions and/or deficiency in cortical inhibitory networks in obese people
Correct Answer: A
Rationale: Reward can trump homeostatic signals dopamine's pull often beats leptin's brake, a false claim busted by obesity's hedonic drive. Regain's wired, liking/wanting's deep, fMRI shows reward overdrive, and corticolimbic rules non-homeostatic. Clinicians tackle this override, a chronic quirk in weight's tug-of-war.
In Netherlands, women who had pregnancy diabetes are advised to be tested regularly for diabetes. Question: This test is an example of which type of prevention?
- A. Universal prevention
- B. Selective prevention
- C. Indicated prevention
- D. Care-related prevention
Correct Answer: C
Rationale: Post-gestational checks indicated, high-risk group, not all, some, or sick. Nurses track this, a chronic red flag watch.
The nurse is admitting an oncology patient to the unit prior to surgery. The nurse reads in the electronic health record that the patient has just finished radiation therapy. With knowledge of the consequent health risks, the nurse should prioritize assessments related to what health problem?
- A. Cognitive deficits
- B. Impaired wound healing
- C. Cardiac tamponade
- D. Tumor lysis syndrome
Correct Answer: B
Rationale: Radiation pre-surgery zaps tissue impaired wound healing's the big risk, as it fries skin and vessels, slowing repair post-op. Cognitive deficits need brain radiation, not specified. Tamponade's rare, tied to chest radiation and fluid buildup. TLS hits post-chemo, not pre-surgery. Nurses in oncology lock onto skin checks and infection signs, knowing radiation's legacy can tank surgical outcomes if ignored.
The best way to prevent chronic complications of diabetes is to:
- A. Take medications as prescribed and remove sugar from the diet completely.
- B. Check feet daily for cuts, long toe nails and infections between the toes.
- C. Maintain a BGL that is as close to normal as possible.
- D. Undertake daily exercise to burn up the excess glucose in the system.
Correct Answer: C
Rationale: Preventing diabetes complications (e.g., neuropathy, retinopathy) hinges on glycemic control. Medications and sugar elimination help, but total sugar removal is impractical carbohydrates are broader, and control, not absence, matters. Daily foot checks prevent ulcers but address consequences, not root causes. Maintaining blood glucose levels (BGL) near normal (e.g., HbA1c <7%) via diet, exercise, and drugs prevents microvascular (kidney, eye) and macrovascular (heart) damage, per ADA guidelines. Exercise burns glucose, aiding control, but isn't singularly best' it's part of a triad. Tight BGL management reduces oxidative stress, glycation, and vascular injury, evidenced by trials (e.g., DCCT), making it the cornerstone strategy over isolated tactics, ensuring long-term organ protection.
