Nursing Elites

1. Which response by the nurse best explains the purpose of ranitidine (Zantac) for a patient admitted with bleeding esophageal varices?

• A. The medication will reduce the risk of aspiration.
• B. The medication will inhibit the development of gastric ulcers.
• C. The medication will prevent irritation of the enlarged veins.
• D. The medication will decrease nausea and improve appetite.

Correct answer: The medication will prevent irritation of the enlarged veins.

Rationale: The correct answer is: 'The medication will prevent irritation of the enlarged veins.' Esophageal varices are dilated submucosal veins. The therapeutic action of H2-receptor blockers in patients with esophageal varices is to prevent irritation and bleeding from the varices caused by reflux of acidic gastric contents. While ranitidine can decrease the risk of peptic ulcers, reduce nausea, and help prevent aspiration pneumonia, the primary purpose of H2-receptor blockade in this patient is to prevent irritation and bleeding from the varices, not the other listed effects.

2. A healthcare professional is reviewing a patient’s chart and notices that the patient suffers from Lyme disease. Which of the following microorganisms is related to this condition?

• A. Borrelia burgdorferi
• B. Streptococcus pyogenes
• C. Bacillus anthracis
• D. Enterococcus faecalis

Correct answer: Borrelia burgdorferi

Rationale: Lyme disease, the most common vector-borne disease in the United States, is caused by the bacterium Borrelia burgdorferi. Borrelia burgdorferi is transmitted to humans through the bite of infected black-legged ticks. Streptococcus pyogenes is associated with strep throat and other infections, not Lyme disease. Bacillus anthracis causes anthrax, a separate infectious disease. Enterococcus faecalis is more commonly linked to urinary tract infections and other healthcare-associated infections, not Lyme disease.

3. A patient with pneumonia has a fever of 101.4 F (38.6 C), a nonproductive cough, and an oxygen saturation of 88%. The patient complains of weakness, fatigue, and needs assistance to get out of bed. Which nursing diagnosis should the nurse assign as the highest priority?

• A. Hyperthermia related to infectious illness
• B. Impaired transfer ability related to weakness
• C. Ineffective airway clearance related to thick secretions
• D. Impaired gas exchange related to respiratory congestion

Correct answer: Impaired gas exchange related to respiratory congestion

Rationale: The correct answer is 'Impaired gas exchange related to respiratory congestion.' While all the nursing diagnoses are relevant to the patient's condition, the priority should be given to impaired gas exchange due to the patient's low oxygen saturation level of 88%. This indicates a significant risk of hypoxia for all body tissues unless the gas exchange is improved. Addressing impaired gas exchange is crucial to ensure adequate oxygenation and prevent further complications. Hyperthermia, impaired transfer ability, and ineffective airway clearance are important concerns but addressing gas exchange takes precedence in this scenario.

4. During shift change, a healthcare professional is reviewing a patient's medication. Which of the following medications would be contraindicated if the patient were pregnant?

• A. Warfarin (Coumadin)
• B. Celecoxib (Celebrex)
• C. Clonidine (Catapres)
• D. Transdermal nicotine (Habitrol)

Correct answer: Warfarin (Coumadin)

Rationale: Warfarin (Coumadin) is contraindicated in pregnancy due to its pregnancy category X classification. It is associated with central nervous system defects, spontaneous abortion, stillbirth, prematurity, hemorrhage, and ocular defects when administered at any time during pregnancy. Fetal warfarin syndrome can occur when given during the first trimester. Celecoxib (Celebrex) is a pregnancy category C medication, which means there may be risks but benefits may outweigh them. Clonidine (Catapres) is also a pregnancy category C drug, and while animal studies have shown adverse effects on the fetus, there are limited human studies. Transdermal nicotine (Habitrol) is classified as a pregnancy category D drug, indicating positive evidence of fetal risk, but benefits may still warrant its use in pregnant women with serious conditions.

5. A fragile 87-year-old female has recently been admitted to the hospital with increased confusion and falls over the last two weeks. She is also noted to have a mild left hemiparesis. Which of the following tests is most likely to be performed?

• A. CBC (Complete Blood Count)
• B. ECG (Electrocardiogram)
• C. Thyroid Function Tests
• D. CT Scan

Correct answer: CT Scan

Rationale: A CT scan is most likely to be performed in this scenario. A CT scan would be done to further investigate the cause of the left hemiparesis. Noncontrast CT scanning is commonly used in the acute evaluation of patients with suspected acute stroke to assess for ischemic changes or hemorrhage in the brain. While a CBC may provide information on blood cell counts and general health status, it is not the primary test for evaluating hemiparesis. An ECG is used to assess heart function and rhythm, which is not the main concern in this case. Thyroid function tests evaluate thyroid hormone levels and are not typically the initial tests for evaluating hemiparesis and confusion.
