Nursing Elites

1. Which system is primarily affected by tuberculosis (Mycobacterium)?

• A. stomach (GI)
• B. heart (cardiac)
• C. lungs (respiratory)
• D. skin (integumentary)

Correct answer: C

Rationale: Tuberculosis, caused by Mycobacterium tuberculosis, primarily affects the respiratory system. This aerobic bacillus thrives in highly oxygenated body sites, such as the lungs, growing ends of bones, and the brain. The bacillus is airborne, making the lungs a common site for infection. Choices A, B, and D are incorrect as tuberculosis predominantly impacts the respiratory system and rarely involves the stomach, heart, or skin.

2. While assessing a patient who has undergone a recent CABG, the nurse notices a mole with irregular edges and a bluish color. What should the nurse do next?

• A. Recommend a dermatological consult to the physician.
• B. Note the location of the mole and contact the physician via telephone.
• C. Note the location of the mole and follow-up with the attending physician through the medical record and a phone call.
• D. Remove the mole with a sharp debridement technique, following approval from the charge nurse.

Correct answer: C

Rationale: In this scenario, the nurse should note the location of the mole and follow up with the attending physician through the medical record and a phone call. This action is appropriate because a mole with irregular edges and a bluish color raises concern for melanoma, a type of skin cancer. Recommending a dermatological consult (Choice A) might delay the evaluation and management of the mole. Contacting the physician via telephone (Choice B) may not provide a documented record of the observation. Removing the mole without proper evaluation (Choice D) could be dangerous and is not within the nurse's scope of practice.

3. Which of the following microorganisms is easily transmitted from client to client on the hands of healthcare workers?

• A. mycobacterium tuberculosis
• B. clostridium tetani
• C. staphylococcus aureus
• D. human immunodeficiency virus

Correct answer: C

Rationale: The correct answer is staphylococcus aureus. Staphylococcus aureus microorganisms are ubiquitous and easily transmitted by healthcare workers who fail to conduct routine hand washing between clients. Staphylococcus aureus can reside on the skin and be transferred from one client to another if proper hand hygiene is not practiced. Mycobacterium tuberculosis is mainly transmitted through the airborne route, clostridium tetani is usually acquired through exposure to soil or dirt contaminated with tetanus spores, and human immunodeficiency virus is not easily transmitted through casual contact or on the hands of healthcare workers.

4. Which of the following symptoms is most characteristic of a client with lung cancer?

• A. exertional dyspnea
• B. persistent changing cough
• C. air hunger; dyspnea
• D. cough with night sweats

Correct answer: B

Rationale: The most characteristic symptom of lung cancer is a persistent changing cough. This cough may worsen over time and may produce blood-tinged sputum. Exertional dyspnea (Choice A) is more common in chronic obstructive pulmonary disease (COPD) due to airway obstruction. Air hunger and dyspnea (Choice C) are more typical of conditions like asthma. Cough with night sweats (Choice D) is commonly associated with tuberculosis rather than lung cancer.

5. When a person using over-the-counter nasal decongestant drops experiences unrelieved and worsening nasal congestion, what should be instructed?

• A. switch to a stronger dose of the same medication.
• B. discontinue the medication for a few weeks.
• C. continue taking the same medication, but use it more frequently.
• D. use a combination of medications for better relief.

Correct answer: B

Rationale: When a person using over-the-counter nasal decongestant drops experiences unrelieved and worsening nasal congestion, it is crucial to discontinue the medication for a few weeks. Prolonged use of decongestant drops can lead to rebound congestion, which is relieved by stopping the medication for a period of time. Nasal congestion occurs due to various factors like infection, inflammation, or allergy, leading to swelling of the nasal cavity. Nasal decongestants work by stimulating alpha-adrenergic receptors, causing vasoconstriction and shrinking of nasal mucous membranes. However, prolonged use can result in vasodilation, worsening nasal congestion. Switching to a stronger dose of the same medication is not recommended as it can exacerbate the issue. Continuing the same medication more frequently or using a combination of medications are also not advised and may lead to side effects. Educating individuals on proper decongestant use and potential risks of prolonged usage is essential, especially for those with specific health conditions.
