Nursing Elites

1. Which of the following white blood cells is the smallest and can be involved in humoral immunity?

• A. Lymphocyte
• B. Monocyte
• C. Basophil
• D. Erythrocyte

Correct answer: A

Rationale: The correct answer is 'Lymphocyte.' Lymphocytes are the smallest type of white blood cells and play a crucial role in humoral immunity by producing antibodies. Monocytes are actually the largest white blood cells and are involved in phagocytosis rather than humoral immunity. Basophils are a type of granulocyte involved in allergic reactions, and erythrocytes are red blood cells responsible for oxygen transport, not part of the immune system.

2. 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.

3. At the beginning of her shift in a long-term care facility, which of the following clients should a nurse check on first?

• A. A 91-year-old man who needs help eating breakfast
• B. An 86-year-old man who has been incontinent in his bed
• C. An 82-year-old woman who needs IV antibiotics
• D. A 75-year-old man who is recovering from an injury and needs an ice pack

Correct answer: C

Rationale: When prioritizing care in a long-term care facility, the nurse must consider tasks that require their immediate attention and cannot be delegated. Administering IV antibiotics is a critical nursing task that only the nurse can perform, ensuring the timely and correct delivery of medication to the patient. While assisting with breakfast, managing incontinence, and providing an ice pack are important, these tasks can be delegated to other healthcare team members, allowing the nurse to address the client needing IV antibiotics first to ensure effective treatment and patient safety.

4. A client has started sweating profusely due to intense heat. His overall luid volume is low and he has developed electrolyte imbalance. This client is most likely suffering from:

• A. Malignant hyperthermia
• B. Heat exhaustion
• C. Heat stroke
• D. Heat cramps

Correct answer: B

Rationale: Heat exhaustion occurs when a person has enough diaphoresis that he becomes dehydrated. Intense sweating can cause both luid and electrolyte imbalances. Untreated heat exhaustion can lead to heat stroke, which results in organ damage, loss of consciousness, or death.

5. Which of the following tasks may be delegated to unlicensed assistive personnel?

• A. Cleansing a wound with peroxide
• B. Irrigating a colostomy
• C. Assisting with performing incentive spirometry
• D. Removing a saline-lock IV

Correct answer: C

Rationale: Certain tasks can be safely delegated to unlicensed assistive personnel to assist nurses in their workload. Tasks that involve routine activities like incentive spirometry can be delegated. Unlicensed assistive personnel can assist clients with incentive spirometry, helping in promoting lung expansion and preventing respiratory complications. Cleansing a wound with peroxide (Choice A) and irrigating a colostomy (Choice B) involve more complex procedures that should be performed by licensed healthcare providers due to the risk of infection and potential complications. Removing a saline-lock IV (Choice D) requires specialized training and should only be performed by licensed personnel to prevent complications and ensure patient safety. The nurse remains responsible for delegating tasks appropriately and overseeing the care provided by unlicensed assistive personnel.
