Mobility is an important human function. The hazards of immobility lead to many physical and emotional problems. Immobility can lead to detrimental cardiac, muscular, respiratory, skeletal, urinary, gastrointestinal, skin, and emotional changes. Which of the following is an example of a skeletal hazard of immobility?
- A. Contractures.
- B. Constipation.
- C. Calcium loss.
- D. Catabolism.
Correct Answer: C
Rationale: All choices are hazards of immobility, but only calcium loss from the bones is a skeletal system impairment that results from immobility. Contractures are muscle shortening due to prolonged positioning, which affects the muscular system. Constipation is a gastrointestinal issue. Catabolism is a metabolic process, not specific to the skeletal system.

Plantar flexion can be prevented with ________________.
- A. foot soaks
- B. foot boards
- C. toenail care
- D. proper shoes
Correct Answer: B
Rationale: Plantar flexion, or foot drop, can be prevented with foot boards, special splints, and range of motion exercises. Foot boards help maintain the foot in a neutral position, preventing contractures and deformities. Foot soaks (choice A) may help with foot hygiene but do not directly prevent plantar flexion. Toenail care (choice C) is important for overall foot health but does not prevent plantar flexion. Proper shoes (choice D) are essential for foot support and comfort but do not specifically prevent plantar flexion.
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.
An occupational health nurse works at a manufacturing plant where there is potential exposure to inhaled dust. Which action, if recommended by the nurse, will be most helpful in reducing the incidence of lung disease?
- A. Treat workers with pulmonary fibrosis.
- B. Teach about symptoms of lung disease.
- C. Require the use of protective equipment.
- D. Monitor workers for coughing and wheezing.
Correct Answer: C
Rationale: Prevention of lung disease requires the use of appropriate protective equipment such as masks to reduce exposure to inhaled dust, which is a significant risk factor for lung disease. Teaching about symptoms of lung disease, treating workers with pulmonary fibrosis, and monitoring for coughing and wheezing are important actions for early recognition and treatment of lung disease. However, the most effective strategy to prevent lung damage in this scenario is to require the use of protective equipment to minimize exposure to harmful substances.
Which of these devices is considered a protective device, rather than a restraint?
- A. A mitten on the hands to prevent scratching
- B. A mitten on the hands to prevent the person from pulling their IV out
- C. A side rail to prevent the patient from falling
- D. A soft wrist restraint to prevent the patient from pulling their IV tubing
Correct Answer: A
Rationale: A mitten on the hands to prevent scratching is considered a protective device because its primary purpose is to protect the patient from harming themselves by scratching. It does not restrict the patient's movement. Choice B, a mitten on the hands to prevent the person from pulling their IV out, is considered a restraint as it limits the patient's movement. Choice C, a side rail to prevent the patient from falling, is also a protective device as it aims to keep the patient safe by providing support and preventing falls. Choice D, a soft wrist restraint to prevent the patient from pulling their IV tubing, is a type of restraint as it restricts the patient's movement to prevent them from interfering with medical equipment.
Your patient has been diagnosed with a left ankle sprain. On the discharge instructions, the physician has prescribed the RICE protocol. This acronym stands for:
- A. Rest, Ice, Compression, Elevation
- B. Radiology, Ice, Compression, Elevation
- C. Rest, Ice, Cast, Elevation
- D. Radiology, Ice, Cast, Elevation
Correct Answer: A
Rationale: The correct answer is Rest, Ice, Compression, Elevation. This acronym, RICE, is commonly used for the treatment of injuries like an ankle sprain. Rest allows the injured area to heal, Ice helps reduce swelling and pain (20 minutes on each hour while awake), Compression is usually achieved with an elastic bandage to minimize swelling, and Elevation of the foot above the level of the heart assists in reducing swelling and promoting healing. Choices B, C, and D are incorrect because they include irrelevant terms like Radiology and Cast, which are not part of the standard treatment protocol for an ankle sprain.
