A study by Epstein & Sowers found that hypertension was X times as prevalent in patients with diabetes compared to the general population. What is X?
- A. Two
- B. Three
- C. Four
- D. Five
Correct Answer: A
Rationale: Diabetes doubles hypertension's odds Epstein & Sowers peg it at two times higher, as insulin resistance and vascular stiffness team up, amplifying prevalence over the general crowd. Three, four, five, or six inflate the risk beyond data, skewing the synergy. This duo's frequent dance tied to shared pathways like RAAS pushes clinicians to screen harder, tackling both to cut cardiovascular and renal doom, a chronic combo grounded in solid stats.

A nurse sets an infusion pump to infuse 1 L of D5NS at the rate of $100 \mathrm{~mL} / \mathrm{hr}$. How many hours will it take to complete the infusion?
- A. 8
- B. 10
- C. 12
- D. 14
Correct Answer: B
Rationale: Math rules IV timing 1 L (1000 mL) at 100 mL/hr divides to 10 hours, a straightforward calc nurses nail for fluid planning. Missteps like 8 or 12 flub the rate; 14's way off. Precision here ensures hydration or med delivery hits the mark, a basic skill keeping care on track.
Autonomic neuropathies affecting people with chronic diabetes affect many body systems. Which of the following is not a clinical manifestation of this problem?
- A. Tachycardia
- B. Mental confusion
- C. Urinary retention
- D. Anhidrosis
Correct Answer: B
Rationale: Diabetes' nerve mess fast heart, pee stalls, no sweat autonomic signs. Confusion's brain sugar or stroke, not this. Nurses clock these, a chronic nerve quirk.
Which of the following nursing interventions would be appropriate for a client with sickle cell disease?
- A. Prepare the client for surgery
- B. Encourage fluid intake
- C. Provide a warm environment
- D. Keep the client strictly NPO
Correct Answer: B
Rationale: Sickle cell's sticky cells crave hydration fluids thin blood, easing vaso-occlusion, a top intervention to cut crisis. Surgery's rare, warmth helps pain, NPO starves. Nurses push intake, preventing sickling, a hydration win in this hemoglobin war.
Regarding oxygen consumption by the adult human body:
- A. It is approximately 3 ml Oâ‚‚ kgâ»Â¹ minâ»Â¹ at rest in the awake adult patient.
- B. It rises to approximately 11 ml Oâ‚‚ kgâ»Â¹ minâ»Â¹ at peak exercise in healthy young adults.
- C. Increases by approximately 5-fold after major surgery.
- D. Peak oxygen consumption is likely to be quantified accurately by cardiopulmonary exercise testing.
Correct Answer: A
Rationale: Oxygen consumption (VOâ‚‚) reflects metabolic demand. At rest, VOâ‚‚ is approximately 3-4 ml Oâ‚‚ kgâ»Â¹ minâ»Â¹ in awake adults, aligning with basal energy needs (250-300 ml/min total). During peak exercise, healthy young adults can reach 30-40 ml Oâ‚‚ kgâ»Â¹ minâ»Â¹, far exceeding 11 ml, depending on fitness. Post-major surgery, VOâ‚‚ increases 50-100% (1.5-2-fold), not 5-fold, due to stress and healing, though critical illness may spike higher briefly. Cardiopulmonary exercise testing (CPET) accurately measures peak VOâ‚‚, unlike the Duke Activity Status Index, which estimates it via questionnaire. The resting value of 3 ml Oâ‚‚ kgâ»Â¹ minâ»Â¹ is a physiological constant, foundational to understanding perioperative oxygen delivery and demand.
The nurse reviews the laboratory results of a patient who is receiving chemotherapy. Which laboratory result is most important to report to the health care provider?
- A. Hematocrit 30%
- B. Platelets 95,000/µL
- C. Hemoglobin 10 g/L
- D. White blood cells (WBC) 2700/µL
Correct Answer: D
Rationale: WBC at 2700/µL post-chemo yells neutropenia infection risk's sky-high, outranking anemia (A, C) or platelets (B bleeding's later, under 20,000). Nurses in oncology report this stat low white cells can spiral to sepsis, a chemo killer needing urgent tweaks.
