Nursing Elites

1. The nurse is discussing the term subculture with a student nurse. Which statement by the nurse would best describe subculture?

• A. "Fitting as many people as possible into the majority culture."?
• B. "Identifying small groups of people who do not want to be identified with the larger culture."?
• C. "Singling out groups of people who suffer differential and unequal treatment as a result of cultural variations."?
• D. "Recognizing groups of people within a culture with shared characteristics that are not common to all members of the culture."?

Correct answer: D

Rationale: A subculture refers to a group of people within a larger culture who share distinct beliefs, values, or attitudes that are not universal among all members of the larger culture. Subcultures can emerge based on factors such as ethnicity, religion, education, occupation, age, and gender. The correct answer describes the concept of a subculture accurately. Choices A, B, and C are incorrect because they do not capture the essence of a subculture. Fitting people into the majority culture, identifying small groups who distance themselves from the larger culture, or singling out individuals facing differential treatment do not define subculture. Subcultures represent specific groups with shared characteristics that differentiate them from the broader cultural norms.

2. Which brain structure serves as the heat-regulating center?

• A. Hypothalamus
• B. Pituitary Gland
• C. Pons
• D. Medulla Oblongata

Correct answer: A

Rationale: The correct answer is the Hypothalamus. The hypothalamus is responsible for regulating body temperature, ensuring it stays within a narrow range. Moreover, the hypothalamus controls various essential bodily functions, such as hunger, thirst, and circadian rhythms. Choices B, C, and D are incorrect because the Pituitary Gland primarily produces and releases hormones, the Pons is involved in functions like sleep, respiration, and bladder control, and the Medulla Oblongata controls vital functions like breathing and heart rate, but not body temperature regulation.

3. When performing a physical examination, safety must be considered to protect the examiner and the patient against the spread of infection. Which of these statements describes the most appropriate action the nurse would take when performing a physical examination?

• A. Washing one's hands after removing gloves is necessary, even if the gloves are still intact
• B. Hands are washed before and after every physical patient encounter
• C. Hands are washed before the examination of each body system to prevent the spread of bacteria from one part of the body to another
• D. Gloves are worn throughout the entire examination to demonstrate concern regarding the spread of infectious diseases

Correct answer: B

Rationale: The most appropriate action for the nurse to take when performing a physical examination is to wash their hands before and after every physical patient encounter. This practice helps prevent the spread of infection. Hands should also be washed after contact with blood, body fluids, secretions, and excretions, and after contact with any equipment contaminated with body fluids. It is crucial to wash hands after removing gloves, even if the gloves appear intact. Choice A is incorrect because washing hands after removing gloves is necessary to ensure thorough hygiene. Choice C is incorrect because hands should be washed before and after every patient encounter, not just before examining each body system. Choice D is incorrect because gloves should be worn when there is potential contact with body fluids, but they do not need to be worn throughout the entire examination.

4. A nurse caring for a client diagnosed with pertussis is ordered to maintain droplet precautions. Which of the following actions of the nurse upholds droplet precautions?

• A. Assign the client to stay in a negative-pressure room
• B. Use sterilized equipment when sharing between this client and another person with pertussis
• C. Wear a mask if coming within 3 feet of the client
• D. Both A and C

Correct answer: C

Rationale: When caring for a client requiring droplet precautions, it is essential for the nurse to wear a mask when within 3 feet of the client. This practice helps prevent the transmission of droplet particles that may be produced when the client coughs or sneezes. Assigning the client to a negative-pressure room is not typically necessary for droplet precautions unless specifically indicated for airborne precautions. Using sterilized equipment when sharing between clients with pertussis is important for infection control but does not directly relate to droplet precautions. Therefore, the correct action to uphold droplet precautions in this scenario is to wear a mask when coming within close proximity to the client.

5. A patient with Parkinson's disease is experiencing difficulty swallowing. What potential problem associated with dysphagia has the greatest influence on the plan of care?

• A. Anorexia
• B. Aspiration
• C. Self-care deficit
• D. Inadequate intake

Correct answer: B

Rationale: When a person experiences dysphagia (difficulty swallowing), the greatest concern is aspiration. Aspiration occurs when food or fluids enter the trachea and lungs instead of going down the esophagus. This can lead to serious complications such as choking, airway obstruction, and aspiration pneumonia. Anorexia (Choice A) refers to a loss of appetite, which is not the primary concern with dysphagia. Self-care deficit (Choice C) and inadequate intake (Choice D) are important considerations but do not have as direct an impact on the immediate safety and health risks associated with aspiration in dysphagia.
