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 of these findings indicate that a pump to deliver a basal rate of 10 ml per hour plus PRN for pain breakthrough for a morphine drip is not working?
- A. The client complains of discomfort at the IV insertion site
- B. The client states 'I just can't get relief from my pain.'
- C. The level of the drug is 100 ml at 8 AM and is 80 ml at noon
- D. The level of the drug is 100 ml at 8 AM and is 50 ml at noon
Correct Answer: C
Rationale: The correct answer is that the level of the drug is 100 ml at 8 AM and is 80 ml at noon. With a basal rate of 10 mL per hour, a total of 40 mL should have been infused by noon, leaving only 60 mL in the container. Any amount greater than 60 mL at noon indicates that the pump is not functioning properly. Therefore, the finding of 80 mL at noon suggests the pump is not delivering the expected medication volume. Choices A and B are related to the client's symptoms and may indicate the need for pain management assessment but do not specifically indicate pump malfunction. Choice D, where the level drops to 50 mL at noon, would actually indicate that the pump is working effectively, as the expected volume has been delivered.
After repair of an inguinal hernia, the infant is being cared for. Which assessment finding indicates that the surgical repair was effective?
- A. A clean, dry incision
- B. Abdominal distension
- C. An adequate flow of urine
- D. Absence of inguinal swelling with crying
Correct Answer: D
Rationale: The absence of inguinal swelling when the infant cries or strains indicates that the surgical repair of the inguinal hernia was effective. Inguinal swelling typically occurs with crying or straining in cases of this condition. A clean, dry incision signifies the absence of wound infection post-surgery but does not directly indicate the effectiveness of the hernia repair. Abdominal distension suggests a gastrointestinal issue unrelated to the hernia repair. An adequate flow of urine is not specific to evaluating the success of inguinal hernia repair.
A child presents to the emergency department with colicky abdominal pain in the lower right quadrant. What disorder is suspected based on these symptoms?
- A. Peritonitis
- B. Appendicitis
- C. Intussusception
- D. Hirschsprung's disease
Correct Answer: B
Rationale: The child's presentation of colicky abdominal pain in the lower right quadrant is classic for appendicitis. Appendicitis typically presents with localized pain that starts near the umbilicus and then shifts to the right lower quadrant. Peritonitis, on the other hand, is characterized by diffuse abdominal pain, tenderness, and guarding, usually resulting from organ perforation or intestinal obstruction. Intussusception is associated with acute, severe abdominal pain and currant jelly-like stools due to intestinal telescoping. Hirschsprung's disease, which lacks ganglion cells in the colon, manifests with symptoms like constipation, abdominal distension, and foul-smelling, ribbon-like stools.
Your patient has shown the following signs and symptoms: Feeling very thirsty, large amount of water intake, dryness of the mouth, and urinary frequency. What physical disorder does this patient most likely have?
- A. Diabetes
- B. Angina
- C. Hypertension
- D. Hypotension
Correct Answer: A
Rationale: The patient is exhibiting classic signs of diabetes, such as polydipsia (feeling very thirsty), polyuria (large amount of water intake and urinary frequency), and xerostomia (dryness of the mouth). These symptoms are indicative of high blood glucose levels, which are characteristic of diabetes. Other common signs of diabetes include poor vision, unexplained weight loss, peripheral neuropathy (tingling in the feet and hands), and fatigue. Angina is chest pain due to reduced blood flow to the heart, not associated with the symptoms described in the patient. Hypertension is high blood pressure, which typically does not present with these specific symptoms related to diabetes. Hypotension is low blood pressure and is not consistent with the signs and symptoms presented by the patient, pointing more towards diabetes as the likely diagnosis.
Which of these individuals would the nurse suspect as having the greatest risk of contracting Hepatitis B?
- A. A sexually active 45-year-old man who has Type 1 Diabetes
- B. A 75-year-old woman who lives in a crowded nursing home
- C. A child who lives in a country with poor sanitation and hygiene standards
- D. A sexually active 23-year-old man who works in a hospital
Correct Answer: D
Rationale: The correct answer is a sexually active 23-year-old man who works in a hospital. This individual is at the highest risk of contracting Hepatitis B due to exposure in a healthcare setting where potential bloodborne pathogens are present. Being sexually active also increases the risk of transmission through sexual contact. Choice A, a 45-year-old man with Type 1 Diabetes, is not directly associated with an increased risk of Hepatitis B. Choice B, a 75-year-old woman living in a crowded nursing home, is at risk for other infections due to the living environment but not specifically for Hepatitis B. Choice C, a child in a country with poor sanitation, is more at risk for water or foodborne illnesses rather than Hepatitis B transmission.
