The nurse educates the client that besides an echocardiogram, which of the following tests is the best tool for diagnosing heart failure?
- A. Pulmonary artery catheter
- B. Mitigated angiographic (MUGA) scan
- C. B-type natriuretic peptide (BNP)
- D. Radionuclide studies
Correct Answer: C
Rationale: BNP, a blood test, spikes with heart stretch heart failure's calling card, outshining invasive tools for diagnosis. Pulmonary catheters measure pressures, not routine. MUGA scans ejection fraction, less direct. Radionuclide's vague here. Nurses teach BNP's ease and accuracy, a biomarker gold standard, syncing with echo to nail heart failure's fluid tale.

Which of the following is an example of multimorbidity?
- A. Chronic obstructive pulmonary disease and a urinary tract infection
- B. Lung cancer and pneumonia
- C. Chronic kidney disease and appendicitis
- D. Diabetes and exacerbation of rheumatoid arthritis
Correct Answer: D
Rationale: Multimorbidity means chronic twins diabetes and rheumatoid arthritis flare together, a dual load, not acute add-ons like UTIs, pneumonia, or appendicitis. Those flare fast and fade; chronic pairs grind on, tangled or not, a nurse's radar for complex care, a hallmark of long-haul illness overlap.
An HIV-positive patient presents to the ED complaining of shortness of breath and non-productive cough. Chest x-ray shows diffuse interstitial infiltrates, and O2 saturation is 85% on room air. All of the following statements regarding this patient's probable diagnosis are TRUE, EXCEPT
- A. Pneumocystis carinii pneumonia (PCP) is the most common opportunistic infection in AIDS patients
- B. Pentamidine isothionate is an effective alternate therapy to TMP-SMX
- C. A normal chest x-ray rules out acute PCP infection
- D. 65% of patients relapse within 18 months
Correct Answer: H
Rationale: PCP top AIDS bug, pentamidine swaps TMP-SMX, relapse hits, steroids for hypoxia; normal CXR misses 20%. Nurses nix this chronic x-ray lie.
Which drug should not be given with midazolam?
- A. zidovudine
- B. lamivudine
- C. nevirapine
- D. indinavir
Correct Answer: D
Rationale: Indinavir boosts midazolam P450 clash sedates too deep, unlike zidovudine, lamivudine, nevirapine, or ritonavir's fit. Nurses dodge this chronic sleep trap.
What do you tell patients is the most important risk factor for lung cancer when you are teaching about lung cancer prevention?
- A. Cigarette smoking
- B. Exposure to environmental/occupational carcinogens
- C. Exposure to environmental tobacco smoke (ETS)
- D. Pipe or cigar smoking
Correct Answer: A
Rationale: Cigarette smoking towers as lung cancer's top risk 80-90% of cases tie to its carcinogens like tar and nicotine, a dose-dependent killer dwarfing other factors. Environmental/occupational exposures like asbestos amplify risk, especially with smoking, but lack its prevalence. ETS hikes risk by 35%, significant yet secondary. Pipe or cigar smoking carries risk, less than cigarettes due to inhalation patterns. Teaching smoking as paramount drives home its preventable dominance, urging cessation as the gold-standard defense, a nurse's key message to slash lung cancer odds, backed by epidemiology and public health campaigns.
Epigenetic changes play a role in the development of type 2 diabetes mellitus. Question: Which of the following statements about epigenetics is correct?
- A. Epigenetic modifications lead to mutations in DNA
- B. Mutations in DNA lead to epigenetic modifications
- C. Epigenetic modifications only take place at a young age
- D. None of the statements provided above is correct
Correct Answer: D
Rationale: Epigenetics tweaks gene dials no mutations, not from mutations, not age-locked. Diet, stress flip switches anytime, a chronic type 2 player nurses note this, no false leads fit.
