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.

Which individual is at greatest risk for developing hypertension?
- A. 45-year-old African-American attorney
- B. 60-year-old Asian-American shop owner
- C. 40-year-old Caucasian nurse
- D. 55-year-old Hispanic teacher
Correct Answer: A
Rationale: African-Americans have a higher risk of developing hypertension compared to other ethnic groups. They tend to develop high blood pressure at younger ages and are more sensitive to salt, which increases their risk of hypertension. Additionally, studies have shown that African-Americans may respond differently to hypertensive drugs. Therefore, the 45-year-old African-American attorney is at the greatest risk for developing hypertension. The other choices do not specify factors that put them at a higher risk for hypertension compared to African-Americans.
The parents of a newborn with a cleft lip are concerned and ask the nurse when the lip will be repaired. With which statement should the nurse respond?
- A. Cleft lip cannot be repaired.
- B. Cleft-lip repair is usually performed by 6 months of age.
- C. Cleft-lip repair is usually performed during the first months of life.
- D. Cleft-lip repair is usually performed between 6 months and 2 years.
Correct Answer: C
Rationale: Cleft-lip repair is typically performed during the first few months of life to address functional and cosmetic concerns at an early stage. Early repair can enhance bonding and facilitate feeding. While revisions may be necessary later on, addressing the cleft lip early is essential. Option A is incorrect as cleft lip repair is a common surgical procedure. Option B is incorrect as repair is typically done earlier than 6 months for better outcomes. Option D is incorrect as the usual timing for repair is within the first months of life, not between 6 months and 2 years.
Septic, anaphylactic, and neurogenic shock are all categorized as:
- A. Hypovolemic shock
- B. Cardiogenic shock
- C. Distributive shock
- D. Obstructive shock
Correct Answer: C
Rationale: Septic, anaphylactic, and neurogenic shock are all types of distributive shock. Distributive shock is characterized by a decrease in systemic vascular resistance, leading to poor tissue perfusion. Septic shock is caused by severe infection, anaphylactic shock is an extreme allergic reaction, and neurogenic shock results from damage to the nervous system. Hypovolemic shock (Choice A) is characterized by a decrease in intravascular volume, cardiogenic shock (Choice B) is due to heart failure, and obstructive shock (Choice D) results from obstruction of blood flow. Therefore, the correct categorization for septic, anaphylactic, and neurogenic shock is distributive shock.
The parents of a child with a hernia are instructed by the nurse on measures to reduce the hernia. Which statement indicates the parents understand the care for their child?
- A. We will encourage our child to cough every few hours on a daily basis.
- B. We will make sure that our child participates in physical activity every day.
- C. We will provide comfort measures to reduce any crying periods by our child.
- D. We will be sure to give our child a Fleet enema every day to prevent constipation.
Correct Answer: C
Rationale: The correct answer is providing comfort measures to reduce any crying periods by the child. This can include offering a warm bath, avoiding upright positioning, and using other comfort measures to reduce crying, which can help reduce a hernia. Encouraging coughing or physical activity can increase strain on the hernia. Giving a Fleet enema daily for constipation is not recommended as it can also increase strain on the hernia.
The nurse is providing discharge instructions to the mother of a child who had a cleft palate repair. Which statement should the nurse make to the mother?
- A. You should use an orthodontic nipple on the child's bottle.
- B. You need to use a plastic spoon to feed the child.
- C. You can allow the child to use a pacifier but only for 30 minutes at a time.
- D. You need to monitor the child's temperature for signs of infection using an oral thermometer.
Correct Answer: A
Rationale: After a cleft palate repair, it is crucial to use an orthodontic nipple on the child's bottle to feed them appropriately. The mother should be instructed to give the child baby food or baby food mixed with water. It is important to avoid introducing straws, pacifiers, spoons, or fingers into the child's mouth for 7 to 10 days post-surgery to prevent complications. The use of a pacifier should be avoided for at least 2 weeks following the surgical repair to promote proper healing. Additionally, taking oral temperatures should be avoided, and alternative temperature monitoring methods should be utilized to reduce the risk of infection. Therefore, options B, C, and D are incorrect because they could potentially lead to complications or hinder the child's recovery after cleft palate repair.
