- B. it involves nonspecific symptoms eg, headache malaise
- C. there is lymphadenopathy
- D. there is a rash, which is pink plaques
Correct Answer: D
Rationale: Secondary syphilis rash spreads, not just pink plaques; timing, malaise, nodes, tests fit. Nurses map this chronic bloom.

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.
A 72 years old man is diagnosed to have Type 2 DM, hypertension and hyperlipidemia with stage 3 chronic kidney disease. He is otherwise well and asymptomatic. He is referred to you for follow-up care. His blood pressure is 142/70 mmHg with HbA1c 6.5%. You would continue his following medications EXCEPT
- A. Hydrochlorothiazide 12.5 mg OD
- B. Simvastatin 40 mg ON
- C. Aspirin 100 mg OD
- D. Glibenclamide 10 mg bid
Correct Answer: D
Rationale: Stage 3 CKD eGFR 30-59 means glibenclamide's out; it piles up, risking hypoglycemia in shaky kidneys. Thiazide holds BP, simvastatin guards lipids, aspirin shields heart, irbesartan protects kidneys all stay. Nurses swap sulphonylureas here, dodging chronic sugar crashes in fragile renal states.
A nurse is caring for a client diagnosed with atherosclerosis. Which of the following is considered a risk factor for the development of this disorder?
- A. Diet high in vitamin K
- B. Low HDL-C/High LDL-C
- C. High HDL-C/Low LDL-C
- D. Vegan diet
Correct Answer: B
Rationale: Atherosclerosis loves lipids low HDL (good cholesterol) and high LDL (bad cholesterol) pile plaque, a prime risk factor driving vessel narrowing. Vitamin K aids clotting, not plaque. High HDL/low LDL protects. Vegan diets cut fats, lowering risk. Nurses flag lipid imbalance, pushing statins or diet shifts, a cholesterol-fueled root of this vascular scourge.
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 caring for a patient who has just been given a 6-month prognosis following a diagnosis of extensive stage small-cell lung cancer. The patient states that he would like to die at home, but the team believes that the patient's care needs are unable to be met in a home environment. What might you suggest as an alternative?
- A. Discuss a referral for rehabilitation hospital
- B. Panel the patient for a personal care home
- C. Discuss a referral for acute care
- D. Discuss a referral for hospice care
Correct Answer: D
Rationale: Extensive small-cell lung cancer with a 6-month clock screams end-stage hospice fits, offering comfort-focused care in settings like home (with support), hospitals, or community sites. It matches his wish to avoid aggressive fixes, unlike rehab (for recovery) or acute care (for crises). Personal care homes lack the palliative punch needed here. Hospice blends patient and family needs, easing symptoms like pain or dyspnea, a cornerstone in oncology for terminal cases where quality trumps quantity.
