1. How does influenza immunization produce immunity?

• A. The virus from the vaccine remains in the body until the end of the season
• B. An attenuated virus causes immune system suppression and triggers immunity
• C. The body identifies the virus and develops antibodies against the virus
• D. The vaccine remains in the injection site and produces immune cells

Correct answer: C

Rationale: The correct answer is C. Influenza immunization works by introducing a weakened or inactivated form of the virus into the body, allowing the immune system to recognize it as foreign. This recognition triggers the production of antibodies specific to the virus. Choice A is incorrect as the virus in the vaccine does not remain in the body until the end of the season. Choice B is incorrect as an attenuated virus does not cause immune system suppression but rather stimulates an immune response. Choice D is incorrect because the vaccine does not stay at the injection site but rather prompts a systemic immune response throughout the body.

2. After studying about viruses, which information indicates the student has a good understanding of viruses? Viruses:

• A. Contain no RNA or DNA
• B. Are capable of independent reproduction
• C. Replicate their genetic material inside host cells
• D. Are killed easily by antimicrobials

Correct answer: C

Rationale: The correct answer is C. Viruses replicate their genetic material inside host cells, which is a fundamental aspect of their life cycle. Choice A is incorrect because viruses contain either RNA or DNA. Choice B is incorrect as viruses cannot reproduce independently and rely on host cells for replication. Choice D is incorrect as viruses are not easily killed by antimicrobials due to their unique structure and mechanisms of infection.

3. After experiencing several months of worsening nocturia, a patient has been assessed for benign prostatic hypertrophy (BPH) and has begun drug treatment. In addition to nocturia, what other sign or symptom is most likely to accompany BPH?

• A. Hematuria
• B. Erectile dysfunction
• C. Urinary frequency
• D. Flank pain

Correct answer: A

Rationale: The correct answer is hematuria. Hematuria, which is the presence of blood in the urine, is a common sign associated with benign prostatic hypertrophy (BPH). It can occur due to irritation or damage to the prostate tissue. While urinary frequency and erectile dysfunction can also be seen in BPH patients, hematuria is more specifically linked to prostate issues. Flank pain is not typically a direct symptom of BPH.

4. A patient presents with a sudden onset of severe chest pain radiating to his back. His blood pressure is significantly higher in the right arm than in the left arm. Which of the following conditions is most likely?

• A. Acute myocardial infarction
• B. Pulmonary embolism
• C. Aortic dissection
• D. Pericarditis

Correct answer: C

Rationale: The correct answer is C, aortic dissection. Aortic dissection is characterized by sudden, severe chest pain that can radiate to the back. The discrepancy in blood pressure between the arms (higher in the right arm) is known as a 'pulse deficit' and is a classic finding in aortic dissection. This condition involves a tear in the inner layer of the aorta, leading to the abnormal flow of blood within the aortic wall. Acute myocardial infarction (choice A) presents with chest pain but typically does not cause discrepancies in blood pressure between arms. Pulmonary embolism (choice B) usually presents with chest pain and difficulty breathing but does not cause unequal blood pressures in the arms. Pericarditis (choice D) can cause chest pain exacerbated by breathing or lying down, but it does not typically lead to differences in blood pressure between arms.

5. A patient has been diagnosed with chronic renal failure. Which of the following agents will assist in raising the patient's hemoglobin levels?

• A. Epoetin alfa (Epogen, Procrit)
• B. Pentoxifylline (Pentoxil)
• C. Estazolam (ProSom)
• D. Dextromethorphan hydrobromide

Correct answer: A

Rationale: The correct answer is A: Epoetin alfa (Epogen, Procrit). Epoetin alfa is a synthetic form of erythropoietin that stimulates red blood cell production and is commonly used to treat anemia in patients with chronic renal failure. By increasing red blood cell production, epoetin alfa helps raise hemoglobin levels in these patients. Pentoxifylline (Choice B) is not indicated for raising hemoglobin levels in chronic renal failure patients; it is a peripheral vasodilator used to improve blood flow. Estazolam (Choice C) is a benzodiazepine used for treating insomnia and has no role in raising hemoglobin levels. Dextromethorphan hydrobromide (Choice D) is a cough suppressant and is not used to raise hemoglobin levels in patients with chronic renal failure.
