Which risk factor places patients and residents at the greatest risk for falls?
- A. Old age
- B. Middle age
- C. Pneumonia
- D. COPD
Correct Answer: A
Rationale: Old age is a significant risk factor for falls as elderly individuals are more prone to falls due to factors like decreased balance, muscle strength, and vision. Middle age is less associated with falls compared to old age. Pneumonia and COPD are medical conditions that are not direct risk factors for falls, unlike aging which significantly increases the risk of falls.

A patient born in 1955 had hepatitis A infection 1 year ago. According to Centers for Disease Control and Prevention (CDC) guidelines, which action should the nurse include in care when the patient is seen for a routine annual physical exam?
- A. Start the hepatitis B immunization series.
- B. Teach the patient about hepatitis A immune globulin.
- C. Ask whether the patient has been screened for hepatitis C.
- D. Test for anti-hepatitis-A virus immune globulin M (anti-HAV-IgM).
Correct Answer: C
Rationale: The correct action for the nurse to include in care when the patient is seen for a routine annual physical exam, according to CDC guidelines, is to ask whether the patient has been screened for hepatitis C. CDC guidelines recommend screening patients born between 1945 and 1965 for hepatitis C due to the high prevalence of undiagnosed cases in this age group. Starting the hepatitis B immunization series is not necessary as the patient already had hepatitis A infection. Teaching the patient about hepatitis A immune globulin is not indicated in this scenario. Testing for anti-hepatitis-A virus immune globulin M (anti-HAV-IgM) is not needed as the patient has already had hepatitis A.
Albert B. is incontinent of urine. He also wears glasses and hearing aids. His ____________lead(s) to his risk for falls.
- A. incontinence and loss of vision
- B. loss of vision
- C. incontinence
- D. loss of hearing
Correct Answer: B
Rationale: Albert B. is at risk for falls due to two factors: his incontinence and his loss of vision. Loss of vision significantly impairs one's ability to navigate and avoid obstacles, thereby increasing the risk of falls. While incontinence is a risk factor for falls, the primary concern in this case is the loss of vision since it directly affects balance and safety. Therefore, the correct answer is 'loss of vision.' Choices A, C, and D are incorrect because they do not address the key factor of impaired vision leading to the risk of falls.
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.
One of the complications of complete bed rest and immobility is which of the following?
- A. Plantar flexion
- B. Dorsiflexion
- C. Extension contractures
- D. Adduction contractures
Correct Answer: A
Rationale: Plantar flexion, or foot drop, is a common complication of complete bed rest and immobility. This condition occurs due to the weakening of muscles that lift the foot, leading to the foot dragging or being unable to clear the ground during walking. Dorsiflexion refers to moving the foot upwards, which is not a typical complication of immobility. Extension contractures involve the inability to fully extend a joint, while adduction contractures refer to the inability to move a limb away from the body. These types of contractures can also occur with immobility, but they are not specifically associated with foot drop.
The nurse teaches a patient about the transmission of pulmonary tuberculosis (TB). Which statement, if made by the patient, indicates that teaching was effective?
- A. I will avoid being outdoors whenever possible.
- B. My husband will be sleeping in the guest bedroom.
- C. I will take the bus instead of driving to visit my friends.
- D. I will keep the windows closed at home to contain the germs.
Correct Answer: B
Rationale: To prevent the transmission of pulmonary tuberculosis, it is important for the infected individual to minimize exposure to close contacts and household members. Sleeping alone in a separate room, like the guest bedroom, is an effective measure. The other choices are not ideal: Choice A is incorrect because spending time outdoors is encouraged for ventilation; Choice C is incorrect as using public transportation increases the risk of transmission; Choice D is incorrect because keeping windows closed limits ventilation, which is necessary to reduce the concentration of infectious particles in the air.
