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. A female patient with atrial fibrillation has the following lab results: Hemoglobin of 11 g/dl, a platelet count of 150,000, an INR of 2.5, and potassium of 2.7 mEq/L. Which result is critical and should be reported to the physician immediately?

• A. Hemoglobin of 11 g/dl
• B. Platelet count of 150,000
• C. INR of 2.5
• D. Potassium of 2.7 mEq/L

Correct answer: D

Rationale: The critical lab result that should be reported to the physician immediately in this case is the potassium level of 2.7 mEq/L. A potassium imbalance, especially in a patient with a history of dysrhythmia like atrial fibrillation, can be life-threatening and lead to cardiac distress. Low potassium levels (hypokalemia) can predispose the patient to dangerous arrhythmias, including worsening atrial fibrillation. Hemoglobin of 11 g/dl, platelet count of 150,000, and an INR of 2.5 are within acceptable ranges and not as immediately concerning as a low potassium level in this clinical context.

3. The nurse is reviewing the characteristics of culture. Which statement is correct regarding the development of one's culture?

• A. Learned through language acquisition and socialization.
• B. Genetically determined on the basis of racial background.
• C. A nonspecific phenomenon and is adaptive but unnecessary.
• D. Biologically determined on the basis of physical characteristics.

Correct answer: A

Rationale: Culture is a complex phenomenon that includes attitudes, beliefs, self-definitions, norms, roles, and values learned from birth through the processes of language acquisition and socialization. It is not biologically or genetically determined, but rather acquired through social interactions. The correct answer, 'Learned through language acquisition and socialization,' aligns with the understanding that culture is a learned behavior. Choices B, C, and D are incorrect because culture is not genetically determined, nonspecific, or biologically based on physical characteristics. Understanding that culture is acquired through language and socialization is essential for healthcare providers to provide culturally competent care.

4. A patient asks the nurse whether he is a good candidate to use a CPAP machine. The nurse reviews the client's history. Which condition would contraindicate the use of a CPAP machine?

• A. The patient is in the late stage of dementia.
• B. The patient has a history of bronchitis.
• C. The patient has had suicidal gestures/attempts in the past.
• D. The patient is on beta-blockers.

Correct answer: A

Rationale: The correct answer is that the patient is in the late stage of dementia. In late-stage dementia, individuals may have an inability to follow commands and understand instructions independently, which are essential for proper installation and use of a CPAP machine. This makes using a CPAP machine challenging and potentially ineffective for patients in this condition. Choice B, having a history of bronchitis, does not contraindicate the use of a CPAP machine. In fact, CPAP therapy can be beneficial for patients with respiratory conditions like bronchitis. Choice C, a history of suicidal gestures/attempts, while concerning for the patient's mental health, does not directly contraindicate the use of a CPAP machine. Choice D, being on beta-blockers, is not a contraindication for CPAP machine use. Beta-blockers are commonly used medications for various conditions and do not interfere with the use of a CPAP machine.

5. While taking the health history of a 70-year-old patient being treated for a Duodenal Ulcer, the nurse learns that the patient is complaining of epigastric pain. What assessment finding would the nurse expect to note?

• A. Melena
• B. Nausea
• C. Hernia
• D. Hyperthermia

Correct answer: A

Rationale: Melena is the passage of black, tarry stools due to the presence of blood in the gastrointestinal tract, usually originating from the upper digestive system. In the context of a Duodenal Ulcer, melena can occur as a result of bleeding in the duodenum or the upper part of the small intestine. This finding is significant as it indicates potential gastrointestinal bleeding, which is a common complication of duodenal ulcers. Nausea (Choice B) is a nonspecific symptom that may be present with various gastrointestinal conditions but is not specific to duodenal ulcers. Hernia (Choice C) involves the protrusion of an organ through the wall of the cavity that normally contains it and is not directly related to the symptoms of a duodenal ulcer. Hyperthermia (Choice D), which refers to an elevated body temperature, is not typically associated with duodenal ulcers unless there are severe complications present.
