Nursing Elites

1. The chain of infection includes the ________________.

• A. germ, agent, reservoir, exit portal, mode of transmission, entry port, and susceptible host
• B. active natural, active artificial, passive natural, and passive artificial
• C. opportunism, weakness, immunity, and colonization
• D. intrinsic, extrinsic, internal, and external transmission

Correct answer: A

Rationale: The chain, or cycle, of infection includes the germ (microorganism), agent, reservoir, exit portal, mode of transmission, entry port, and susceptible host. This sequence describes how infections are passed from one person to another. Choice B is incorrect because it refers to types of immunity, not components of the chain of infection. Choice C is also incorrect as it lists terms unrelated to the chain of infection. Choice D is incorrect as it describes transmission types, not components of the chain of infection. Understanding the chain of infection is crucial in preventing the spread of infections by breaking one or more links in the chain, such as interrupting the mode of transmission through proper hand hygiene.

2. A nurse is performing an end-of-shift count of narcotics kept in the locked cabinet. The narcotic log states there should be 26 oxycodone pills left, but there are only 24 in the drawer. What is the first action of the nurse?

• A. Perform the count again
• B. Contact the pharmacy to determine if the narcotic log is incorrect
• C. Check with the last nurse to sign out narcotics from the system
• D. Notify the house supervisor that narcotic medications are missing

Correct answer: A

Rationale: The first action the nurse should take in this situation is to perform the count again. This step is crucial to ensure there was no miscount during the initial check. By verifying the count, the nurse can confirm if there is indeed a discrepancy in the number of oxycodone pills. Contacting the pharmacy, checking with the last nurse, or notifying the house supervisor should only be considered after ensuring the count is accurate. It's important to rule out any human error before escalating the issue to others.

3. You are taking care of Mary Eden, an elderly and frail 91-year-old resident. She gets confused during evening hours and at times she thinks that she hears her daughter calling her from the other side of the nursing home. Which physical problem places Mary Eden at risk for falls?

• A. Her confusion
• B. Her daughter
• C. Evening hours
• D. Her frailness

Correct answer: D

Rationale: Mary Eden's frail and weak muscles due to her age and physical condition place her at risk for falls. While her confusion can contribute to falls, it is considered an emotional or cognitive issue rather than a physical problem. Her daughter and the evening hours are not physical problems that directly increase her risk of falling.

4. A client must use a non-rebreathing oxygen mask. Which of the following statements is true regarding this type of mask?

• A. A non-rebreather can provide an FiO2 of 40%.
• B. A client should breathe through his or her mouth when using a non-rebreather.
• C. A non-rebreather offers a reservoir from which the client inhales.
• D. The mask of a non-rebreather should be changed every 3 hours.

Correct answer: A

Rationale: A non-rebreather mask is used for supplemental oxygen delivery for clients experiencing breathing difficulties. The non-rebreather mask includes a one-way valve that allows exhaled air to escape, preventing the rebreathing of carbon dioxide. The client inhales oxygenated air from a reservoir bag attached to the mask, providing high-concentration oxygen therapy. A non-rebreather mask can deliver FiO2 levels of up to 90%, making it an effective intervention for clients requiring high oxygen concentrations. Therefore, the statement that 'A non-rebreather can provide an FiO2 of 40%' is correct. Choices B, C, and D are incorrect because clients should breathe through their nose and mouth, the mask offers a reservoir for inhaling oxygen, and the mask should be assessed and potentially replaced if soiled or damaged, not routinely changed every 3 hours.

5. You are caring for a patient with newly diagnosed multiple sclerosis. Discharge instructions will likely include all of the following EXCEPT:

• A. PT referral for development of a planned exercise program
• B. Avoidance of prolonged sun exposure
• C. Hot baths to promote muscle relaxation
• D. Instructions to evaluate the home environment to ensure safety

Correct answer: C

Rationale: Discharge instructions for a patient with newly diagnosed multiple sclerosis should focus on promoting safety and minimizing exacerbations. Hot baths should be avoided as excessive heat can trigger acute symptoms. Therefore, instructions may include PT referral for an exercise program to maintain mobility, avoidance of prolonged sun exposure to prevent symptom exacerbation, and guidance to evaluate the home environment for safety as symptoms progress. Hot baths are not recommended due to the risk of exacerbating symptoms, making it the correct answer. Choices A, B, and D are appropriate for a patient with multiple sclerosis, as they address mobility, symptom management, and safety concerns, respectively.
