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. Tommy R., your 68-year-old patient, is at risk for falls. He has fallen 3 times in the last month. You should keep Tommy's ______________ in order to prevent him from falling again.

• A. bedside rails up at all times
• B. bed in the low position
• C. call bell within reach
• D. family members in the room at all times

Correct answer: C

Rationale: To prevent falls, it is essential to keep the patient's call bell within reach so they can easily call for help when needed. This allows for timely assistance and can prevent falls. While low beds can reduce the severity of injuries in case of a fall, they do not prevent falls from happening. Having family members in the room at all times is not a realistic or practical solution. Side rails can actually increase the severity of falls as patients may attempt to climb over them, and using side rails as fall prevention is considered a restraint practice that can lead to entrapment and other risks.

3. A patient who has been diagnosed with vasospastic disorder (Raynaud's disease) complains of cold and stiffness in the fingers. Which of the following descriptions is most likely to fit the patient?

• A. An adolescent male
• B. An elderly woman
• C. A young woman
• D. An elderly man

Correct answer: C

Rationale: The correct answer is 'A young woman.' Raynaud's disease is most common in young women and is often associated with rheumatologic disorders like lupus and rheumatoid arthritis. This disorder involves vasospasm of the arteries, leading to reduced blood flow to the fingers and toes. Typically, Raynaud's affects the fingers, and in some cases, it can affect the toes. Only rarely does it involve other body parts such as the nose, ears, nipples, and lips. Choices B, C, and D are less likely as Raynaud's disease predominantly affects young women, although it can occur in other demographic groups as well.

4. 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.

5. A new mother has some questions about phenylketonuria (PKU). Which of the following statements made by a nurse is not correct regarding PKU?

• A. A Guthrie test can check the necessary lab values.
• B. The urine has a high concentration of phenylpyruvic acid
• C. Mental deficits are often present with PKU
• D. The effects of PKU are reversible

Correct answer: D

Rationale: Phenylketonuria (PKU) is an inherited disorder that increases the levels of phenylalanine (a building block of proteins) in the blood. If PKU is not treated, phenylalanine can build up to harmful levels in the body, causing intellectual disability and other serious health problems. The signs and symptoms of PKU vary from mild to severe. The most severe form of this disorder is known as classic PKU. Infants with classic PKU appear normal until they are a few months old. Without treatment, these children develop a permanent intellectual disability. Seizures, delayed development, behavioral problems, and psychiatric disorders are also common. Untreated individuals may have a musty or mouse-like odor as a side effect of excess phenylalanine in the body. Children with classic PKU tend to have lighter skin and hair than unaffected family members and are also likely to have skin disorders such as eczema. The effects of PKU stay with the infant throughout their life (via Genetic Home Reference).
