A nurse is assessing a client with chronic liver failure who tells the nurse he is experiencing spontaneous episodes of bleeding and has noted increased areas of bruising on his arms. The nurse suspects the client has a deficiency in which of the following vitamins?

Thiamine

Vitamin C

Vitamin K

Folic acid

Answer and Explanation

The Correct Answer is C

A. Thiamine deficiency is often associated with neurological symptoms, such as Wernicke-Korsakoff syndrome, rather than spontaneous bleeding or bruising. Thiamine does not directly impact the coagulation process.
B. Vitamin C deficiency can lead to scurvy, which includes symptoms such as bleeding gums and poor wound healing. However, it is not typically associated with the spontaneous bleeding and bruising seen in chronic liver failure.
C. Vitamin K is essential for the synthesis of clotting factors produced by the liver. In chronic liver failure, the liver's ability to produce these factors is impaired, leading to an increased risk of bleeding and bruising due to vitamin K deficiency.
D. Folic acid deficiency is more commonly linked to anemia and certain neurological issues, but it does not cause spontaneous bleeding or bruising. It does not directly affect coagulation factors as vitamin K does.

Correct Answer is A

Explanation

A. Keeping a body map of skin lesions is a key strategy for monitoring changes in the skin over time. This helps individuals track any new or changing lesions, which is crucial for early detection of skin cancer.
B. Reducing tanning bed use is important because tanning beds are a significant risk factor for skin cancer. However, the instruction should emphasize complete avoidance rather than just reduction, as tanning beds dramatically increase the risk of melanoma.
C. Examining your body every 2 months is not frequent enough for effective skin cancer monitoring. Monthly self-examinations are generally recommended to catch potential changes early.
D. Avoiding the sun after 3 p.m. is incorrect; the most dangerous sun exposure typically occurs between 10 a.m. and 4 p.m. The instruction should advise avoiding the sun during peak hours or wearing protective clothing and sunscreen.

A. Encourage the client to increase fluid intake. B. Wear a mask when caring for the client. C. Prepare to administer an antibiotic to the client. D. Place the client in a private room. E. Place the client on contact precautions.

Correct Answer is ["A","B","D"]

Explanation

A. Encourage the client to increase fluid intake: This is important to prevent dehydration, which can be a complication of influenza.
B. Wear a mask when caring for the client: Influenza is a highly contagious virus, and wearing a mask can help prevent the spread of infection.
C. Prepare to administer an antibiotic to the client: Antibiotics are not typically used to treat influenza, which is a viral infection. However, if a bacterial infection develops as a complication, antibiotics may be necessary.
D. Place the client in a private room: Isolating the client in a private room can help prevent the spread of influenza to other patients and healthcare workers.
E. Place the client on contact precautions: Influenza is primarily spread through respiratory droplets, so droplet precautions are appropriate. Contact precautions are not necessary for influenza.
