The nurse is caring for several clients on a hospital unit. Which of the following clients is most at risk for hypoglycemia?
A client with type 1 diabetes mellitus who has taken a high dose of insulin
A client who has type 2 diabetes and has not taken any medication
An older adult client taking an antibiotic for an infection
A client who has metabolic syndrome and is taking a statin drug to lower cholesterol levels
The Correct Answer is A
Choice A reason: A client with type 1 diabetes mellitus who has taken a high dose of insulin is at significant risk for hypoglycemia. In type 1 diabetes, the body does not produce insulin, so insulin therapy is essential for controlling blood glucose levels. However, if the dose of insulin is too high relative to the patient's dietary intake or physical activity level, it can lead to a rapid decrease in blood glucose levels, resulting in hypoglycemia. Hypoglycemia is defined as a blood glucose level less than 70 mg/dL (3.9 mmol/L) and can cause symptoms such as confusion, sweating, weakness, and in severe cases, seizures or loss of consciousness.
Choice B reason: A client with type 2 diabetes who has not taken any medication may have elevated blood glucose levels but is not typically at immediate risk for hypoglycemia unless they are taking medications that lower blood glucose. Type 2 diabetes is characterized by insulin resistance, and while medication can help manage it, skipping medication does not usually result in hypoglycemia unless other factors are at play.
Choice C reason: An older adult client taking an antibiotic for an infection is not generally at risk for hypoglycemia unless the antibiotic interacts with other medications that the client is taking for diabetes management. Antibiotics themselves do not typically cause hypoglycemia.
Choice D reason: A client who has metabolic syndrome and is taking a statin drug to lower cholesterol levels is not at direct risk for hypoglycemia from the statin medication. Metabolic syndrome is a cluster of conditions that increase the risk for heart disease, stroke, and type 2 diabetes. While statins are used to lower cholesterol levels, they do not have a direct impact on blood glucose levels that would lead to hypoglycemia.

Correct Answer is A
Explanation
Choice A reason: White rice is considered a low-potassium food, making it a suitable option for someone with chronic kidney disease who needs to limit their potassium intake. One cup of cooked white rice contains approximately 54 mg of potassium, which is significantly lower than the other options listed.
Choice B reason: Nonfat yogurt can vary in potassium content, but on average, a 1/2 cup serving may contain around 200 to 300 mg of potassium. While it is a nutritious choice, it contains more potassium than white rice and should be consumed in moderation by individuals with potassium restrictions.
Choice C reason: A medium baked potato with skin is high in potassium, with one potato containing over 900 mg of potassium. This makes it an unsuitable choice for someone who needs to limit their potassium intake due to chronic kidney disease.
Choice D reason: Peanut butter contains a moderate amount of potassium. Two tablespoons of peanut butter can have around 150 to 200 mg of potassium. Although it's not as high in potassium as a baked potato, it still contains more potassium than white rice.
Correct Answer is B
Explanation
Choice A reason: The Mantoux skin test, also known as the tuberculin skin test, measures the immune response to the tuberculin purified protein derivative (PPD) injected under the skin. An induration of less than 1 mm is not necessarily an indication of non-infectiousness; it may indicate a lack of infection or an inadequate immune response. This test does not reflect the current infectious status as it measures a delayed hypersensitivity reaction and can remain positive for life once someone has been exposed to TB or has received the BCG vaccine.
Choice B reason: Negative sputum cultures for acid-fast bacillus are a strong indication that the client is no longer infectious. Pulmonary tuberculosis is diagnosed and monitored through sputum cultures to detect the presence of Mycobacterium tuberculosis. A series of negative cultures typically indicates that the client is not excreting the bacteria and is, therefore, not contagious.
Choice C reason: While the cessation of coughing up blood-tinged sputum is a positive sign of clinical improvement, it does not conclusively indicate that the client is no longer infectious. The absence of blood in the sputum may simply mean that the damage to lung tissues is healing, but the client could still be harboring and potentially spreading TB bacteria.
Choice D reason: The Quantiferon-TB Gold test is a blood test that measures the immune system's response to TB bacteria. A positive result indicates TB infection, but it does not distinguish between latent infection and active disease, nor does it provide information on infectiousness. The parenthetical "negative" is confusing and should be clarified in the context of the test results.
