1. A patient is hospitalized with active tuberculosis. The patient is receiving antitubercular drug therapy and is not responding to the medications. What do you suspect the patient is suffering from?

A. Human immunodeficiency virus
B. Drug-resistant tuberculosis
C. Methicillin-resistant Staphylococcus aureus
D. Vancomycin-resistant Staphylococcus aureus

Correct answer: B

Rationale: When a patient with active tuberculosis is not responding to antitubercular drug therapy, drug-resistant tuberculosis should be suspected. Drug-resistant tuberculosis occurs when the bacteria causing tuberculosis become resistant to the medications being used. Choices A, C, and D are incorrect because the scenario described does not align with HIV infection, methicillin-resistant Staphylococcus aureus, or vancomycin-resistant Staphylococcus aureus.

2. A 30-year-old male has been brought to the emergency department by his wife because of a severe headache, nausea, vomiting, and fever. A lumbar puncture is performed, and cerebrospinal fluid (CSF) analysis reveals a high protein count, low glucose, and numerous polymorphonuclear leukocytes (PMNs). Which organism is the most likely cause of these findings?

A. Streptococcus pneumoniae
B. Neisseria meningitidis
C. Escherichia coli
D. Listeria monocytogenes

Correct answer: A

Rationale: The cerebrospinal fluid (CSF) analysis findings of high protein count, low glucose, and numerous polymorphonuclear leukocytes (PMNs) are classic for bacterial meningitis. Among the choices, Streptococcus pneumoniae is the most likely cause in this case. Streptococcus pneumoniae is a common cause of bacterial meningitis in adults, especially presenting with symptoms such as severe headache, nausea, vomiting, and fever. Neisseria meningitidis is another common cause of bacterial meningitis but is more frequently associated with a different CSF profile. Escherichia coli is a common cause of neonatal meningitis, not typically seen in a 30-year-old male. Listeria monocytogenes is more commonly associated with meningitis in immunocompromised individuals and neonates, and typically presents differently in CSF analysis.

3. Which of the following describes passive immunity?

A. Vaccination against the disease
B. Transfer of antibodies from mother to baby
C. Cuts or wounds that are infected and heal
D. Having the disease in question

Correct answer: B

Rationale: Passive immunity is the transfer of pre-formed antibodies from one individual to another, providing immediate but temporary protection. In this case, the correct answer is the transfer of antibodies from the mother to the baby, as it describes the concept of passive immunity. Choice A, vaccination against the disease, refers to active immunity where the individual's immune system is stimulated to produce antibodies. Choice C, cuts or wounds that are infected and heal, is unrelated to immunity. Choice D, having the disease in question, does not describe passive immunity but rather acquiring active immunity through exposure to the pathogen.

4. A 1-year-old child will receive her scheduled MMR vaccination shortly. The nurse should teach the child's parents that she may develop what possible adverse effect related to the administration of this vaccine?

A. Cough and fever
B. Pallor and listlessness
C. Serum sickness
D. Nausea and vomiting

Correct answer: A

Rationale: The correct answer is A: Cough and fever. After receiving the MMR vaccine, some children may experience mild adverse effects such as a low-grade fever and a mild cough. These symptoms are normal reactions to the vaccine and indicate that the child's immune system is responding appropriately. Choices B, C, and D are incorrect because pallor and listlessness, serum sickness, nausea, and vomiting are not common adverse effects associated with the MMR vaccine in children.

5. A 55-year-old male patient is taking finasteride (Proscar) for benign prostatic hyperplasia (BPH). What patient teaching should the nurse provide regarding the use of this medication?

A. Avoid taking over-the-counter antacids while on this medication.
B. This medication may decrease libido.
C. This medication may take several months to improve symptoms.
D. This medication may cause increased hair growth.

Correct answer: C

Rationale: Correct Answer: The nurse should inform the patient that finasteride may take several months to improve symptoms of BPH. It is essential for patients to understand the delayed onset of action to manage their expectations and compliance. Choice A is incorrect because there is no significant interaction between finasteride and over-the-counter antacids. Choice B is incorrect as finasteride is more commonly associated with decreased libido rather than increased libido. Choice D is incorrect as finasteride is known to reduce hair growth rather than increase it.
