Nursing Elites

1. A patient with idiopathic pulmonary arterial hypertension (IPAH) is receiving nifedipine (Procardia). Which assessment would best indicate to the nurse that the patient's condition is improving?

• A. Blood pressure (BP) is less than 140/90 mm Hg.
• B. Patient reports decreased exertional dyspnea
• C. Heart rate is between 60 and 100 beats/minute
• D. Patient's chest x-ray indicates clear lung fields

Correct answer: B

Rationale: The correct answer is for the patient to report decreased exertional dyspnea. In idiopathic pulmonary arterial hypertension (IPAH), exertional dyspnea is a significant symptom indicating disease severity. Improvement in this symptom suggests that the medication, nifedipine, is effective in managing the condition. While nifedipine can affect blood pressure (choice A) and heart rate (choice C), these parameters are not specific indicators for monitoring IPAH improvement. Choice D, clear lung fields on the chest x-ray, does not directly correlate with the effectiveness of therapy for IPAH. Therefore, the most relevant assessment to monitor improvement in a patient with IPAH receiving nifedipine is a decrease in exertional dyspnea.

2. 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.

3. After assessing Mr. B, what is the initial action of the nurse?

• A. Immediately place the client in a negative-pressure room
• B. Set the client up to receive a bronchoscopy
• C. Contact the physician for antifungal medications
• D. Administer oxygen and assist the client to sit in the semi-Fowler's position

Correct answer: A

Rationale: The first action the nurse should take after assessing Mr. B is to administer oxygen and assist him to sit in the semi-Fowler's position. Administering oxygen helps improve tissue oxygenation, while sitting up in a semi-Fowler's position aids in better breathing and secretion clearance. Placing the client in a negative-pressure room is not the immediate priority unless isolation is needed. Performing a bronchoscopy or contacting the physician for antifungal medications is not the initial step in managing a client with suspected pneumonia.

4. Mr. B is recovering from a surgical procedure that was performed four days ago. The nurse's assessment finds this client coughing up rust-colored sputum; his respiratory rate is 28/minute with expiratory grunting, and his lung sounds have coarse crackles on auscultation. Which of the following conditions is the most likely cause of these symptoms?

• A. Tuberculosis
• B. Pulmonary edema
• C. Pneumonia
• D. Histoplasmosis

Correct answer: C

Rationale: In this scenario, the client's presentation of coughing up rust-colored sputum, increased respiratory rate, expiratory grunting, and coarse crackles on lung auscultation suggests the development of pneumonia. Pneumonia is characterized by lung tissue inflammation or infection, often caused by various organisms. Symptoms may include productive cough, dyspnea, and abnormal breath sounds. Tuberculosis (Choice A) typically presents with a chronic cough, weight loss, and night sweats and is less likely in this acute post-operative setting. Pulmonary edema (Choice B) is characterized by pink, frothy sputum, crackles throughout the lungs, and typically occurs in the context of heart failure. Histoplasmosis (Choice D) is a fungal infection that usually presents with flu-like symptoms and is less likely to manifest with the specific respiratory findings described in this case.

5. Which of the following can cause coup-contrecoup injuries?

• A. Rotational forces
• B. Deformation forces
• C. Deceleration forces
• D. Acceleration forces

Correct answer: C

Rationale: Deceleration forces occur when the head is moving and abruptly comes to a stop, such as in a car crash. This sudden deceleration can cause the brain to hit against the skull, resulting in coup-contrecoup injuries. In a coup-contrecoup injury, the brain is damaged on opposite sides due to the initial impact and the rebound effect inside the skull. Rotational forces usually result in diffuse axonal injuries rather than coup-contrecoup injuries. Deformation forces can cause focal brain injuries but not coup-contrecoup injuries. Acceleration forces typically lead to diffuse brain injuries, not coup-contrecoup injuries. Therefore, the correct answer is deceleration forces.
