Nursing Elites

1. What is the most effective way to limit the number of microorganisms in the hospital?

• A. Using strict aseptic technique in all procedures
• B. Wearing a mask and gown when caring for all patients with communicable diseases
• C. Sterilizing all instruments
• D. Handwashing

Correct answer: A

Rationale: The most effective way to limit the number of microorganisms in the hospital is by using strict aseptic technique in all procedures. This approach ensures that the risk of introducing harmful microorganisms into the hospital environment or patients is minimized. Choice B, wearing a mask and gown when caring for patients with communicable diseases, is important but not as comprehensive as using aseptic technique in all procedures. Sterilizing all instruments (Choice C) is crucial for preventing infections but may not address all avenues of microorganism transmission. Handwashing (Choice D) is a fundamental practice in infection control but alone may not be as effective as utilizing aseptic techniques in all procedures to limit microorganisms in the hospital.

2. Which bond is formed by a positively charged metal ion and negatively charged nonmetal ion?

• A. Ionic bond
• B. Covalent bond
• C. Functional group
• D. Metallic bond

Correct answer: A

Rationale: The correct answer is an ionic bond. An ionic bond is formed when a positively charged metal ion joins with a negatively charged nonmetal ion, resulting in a transfer of electrons. In contrast, a covalent bond involves sharing electrons between atoms rather than complete transfer. Functional groups are specific groups of atoms within molecules that determine the molecule's chemical properties. Metallic bonds occur between metal atoms where electrons are shared across a delocalized electron cloud.

3. Which of the following are the primary bacteria involved in the initiation of dental caries?

• A. Streptococcus mutans and Lactobacillus species
• B. Salmonella and Listeria species
• C. Streptococcus, Lactobacillus, and Salmonella species
• D. Listeria, Botulinum species, and Escherichia coli

Correct answer: A

Rationale: The correct answer is A: Streptococcus mutans and Lactobacillus species. These bacteria are primarily responsible for initiating dental caries by fermenting carbohydrates and producing acids that demineralize enamel. Choice B, Salmonella and Listeria species, are not the primary bacteria involved in dental caries. Choice C includes Salmonella which is not a primary culprit in dental caries. Choice D lists Listeria, Botulinum species, and Escherichia coli, none of which are the primary bacteria associated with initiating dental caries.

4. The nurse notes that the fall might also cause a possible head injury. The patient will be observed for signs of increased intracranial pressure which include:

• A. Narrowing of the pulse pressure
• B. Vomiting
• C. Periorbital edema
• D. A positive Kernig's sign

Correct answer: C

Rationale: Periorbital edema is a sign of increased intracranial pressure. It is caused by fluid accumulation around the eyes due to compromised drainage. Narrowing of the pulse pressure is more indicative of shock than increased intracranial pressure. While vomiting can be a sign of increased intracranial pressure, it is not as specific as periorbital edema. A positive Kernig's sign is associated with meningitis, not increased intracranial pressure.

5. Where is Vitamin K synthesized?

• A. by bacteria in the GI tract
• B. by the body by sunlight
• C. deficiency is called beriberi
• D. found in vegetable oils

Correct answer: A

Rationale: Vitamin K is synthesized by bacteria in the gastrointestinal tract. Choice B is incorrect as the synthesis of Vitamin D, not K, can be induced by sunlight exposure. Choice C is incorrect as beriberi is a condition caused by thiamine (Vitamin B1) deficiency, not Vitamin K. Choice D is incorrect as Vitamin E is commonly found in vegetable oils, not Vitamin K.
