1. What is the cause of meningitis that is fatal in half of the infected patients?

• A. Virus
• B. Bacteria
• C. Fungus
• D. Noninfectious agent

Correct answer: B

Rationale: Bacterial meningitis is caused by bacterial pathogens such as Streptococcus pneumoniae, Haemophilus influenzae, Listeria monocytogenes, and Neisseria meningitidis. These bacteria commonly lead to acute onset meningitis, presenting with symptoms like fever, stiff neck, and altered consciousness. The statement that bacterial meningitis is fatal in about 50% of cases is accurate, making it a serious and life-threatening condition. Viruses can also cause meningitis, but they are not typically associated with the high fatality rate seen in bacterial meningitis. Fungal meningitis is less common and usually affects individuals with weakened immune systems. Noninfectious agents do not cause meningitis.

2. Which pathologic condition is described as 'increased intraocular pressure of the eye'?

• A. Detached Retina
• B. Fovea Centralis
• C. Presbyopia
• D. Glaucoma

Correct answer: D

Rationale: The correct answer is Glaucoma. Glaucoma is a condition characterized by increased intraocular pressure in the eye, which can lead to optic nerve damage, vision loss, and blindness if left untreated. Detached Retina (A), Fovea Centralis (B), and Presbyopia (C) are not conditions associated with increased intraocular pressure like Glaucoma. Detached Retina is a separation of the retina from its underlying tissue, Fovea Centralis is a part of the retina responsible for sharp central vision, and Presbyopia is an age-related condition affecting near vision due to the loss of flexibility in the eye's lens.

3. When assessing the respiratory system of an older patient, which finding indicates that the nurse should take immediate action?

• A. Weak cough effort
• B. Barrel-shaped chest
• C. Dry mucous membranes
• D. Bilateral crackles at lung bases

Correct answer: D

Rationale: Bilateral crackles at lung bases indicate a potential acute issue like heart failure. Immediate action is necessary in this situation. The nurse should conduct further assessments such as oxygen saturation and inform the healthcare provider promptly. A barrel-shaped chest and hyperresonance to percussion are typical signs of aging and do not require immediate action. A weak cough effort is common in older patients due to age-related changes, and dry mucous membranes are also expected in older individuals. While these findings may warrant further evaluation, they do not demand immediate action like bilateral crackles at lung bases.

4. A 24-year-old female contracts hepatitis from contaminated food. During the acute (icteric) phase of the patient's illness, what would serologic testing most likely reveal?

• A. antibody to hepatitis D (anti-HDV).
• B. hepatitis B surface antigen (HBsAg).
• C. anti-hepatitis A virus immunoglobulin G (anti-HAV IgG).
• D. anti-hepatitis A virus immunoglobulin M (anti-HAV IgM).

Correct answer: D

Rationale: Hepatitis A is primarily transmitted through the oral-fecal route. During the acute phase of hepatitis A, serologic testing typically reveals anti-hepatitis A virus immunoglobulin M (anti-HAV IgM). This antibody appears early in the course of the infection. The presence of anti-HAV IgM indicates an acute infection with hepatitis A. Choices A and B are incorrect as hepatitis D and hepatitis B antigens are not typically associated with acute hepatitis A. Choice C, anti-hepatitis A virus immunoglobulin G (anti-HAV IgG), would indicate a past infection and lifelong immunity, which is not expected during the acute phase of the illness.

5. The nurse is teaching parents about the treatment plan for a 2-week-old infant with Tetralogy of Fallot. While awaiting future surgery, the nurse instructs the parents to immediately report

• A. Loss of consciousness
• B. Feeding problems
• C. Poor weight gain
• D. Fatigue with crying

Correct answer: A

Rationale: The correct answer is 'Loss of consciousness.' While parents should report any concerning observations, they need to call the healthcare provider immediately if the infant experiences a loss of consciousness. This change in alertness may indicate anoxia, which can be life-threatening. Tetralogy of Fallot is a congenital heart defect characterized by four main features: pulmonic stenosis, ventricular septal defect, overriding aorta, and right ventricular hypertrophy. Surgery for Tetralogy of Fallot may be delayed or done in stages. Reporting loss of consciousness is crucial due to the potential seriousness of the condition. Feeding problems, poor weight gain, and fatigue with crying are important issues but do not require immediate reporting like loss of consciousness does.
