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 B

Explanation

A. Decreased prothrombin time is not typically associated with the emergent phase of a burn injury. Prothrombin time changes are more related to liver function or coagulation disorders.
B. Increased hematocrit is common in the emergent/resuscitative phase of burn injury due to fluid shifts and loss of plasma volume, leading to hemoconcentration.
C. Increased sodium is not typically seen in the emergent phase; instead, hyponatremia may occur due to fluid shifts and loss of sodium in the burn exudate.
D. Potassium deficit is more likely to occur later in the burn management phases. In the emergent phase, hyperkalemia is more common due to cell destruction and release of intracellular potassium.

A. Osteoarthritis B. Place of employment C. Gentamycin D. Naproxen E. Bumetanide F. Heart failure

Correct Answer is ["B","C","D","E"]

Explanation

A. Osteoarthritis is not associated with hearing loss
B. The client's place of employment as a firearms instructor at a shooting range exposes them to loud noises, which is a well-known risk factor for hearing loss.
C. Gentamycin is an aminoglycoside antibiotic that can be ototoxic, especially when administered in high doses or for prolonged periods, potentially leading to hearing loss.
D. Naproxen is a nonsteroidal anti-inflammatory drug (NSAID) that has been associated with an increased risk of hearing loss, particularly when taken regularly or in high doses.
E. Bumetanide is a loop diuretic that can also have ototoxic effects, especially when used in conjunction with aminoglycoside antibiotics like gentamycin.
F. Heart failure is not associated with hearing loss
