A nurse is checking the laboratory results of a client who is at risk for diabetes mellitus. Which of the following laboratory results indicates to the nurse that the client is at risk for diabetes mellitus?

Choice A rationale
Regular insulin should be clear. If it appears cloudy, it may be contaminated or expired, and should be discarded. This is a correct instruction for self-administering regular insulin and NPH insulin from the same syringe.
Choice B rationale
When mixing insulins, regular insulin should be drawn up first, followed by NPH insulin. Drawing up NPH insulin first can lead to contamination of the regular insulin with the cloudy NPH insulin.
Choice C rationale
NPH insulin should be gently rolled or inverted to mix, not shaken. Shaking can cause bubbles, which can lead to inaccurate dosing.
Choice D rationale

Air should be injected into the NPH insulin vial first, not the regular insulin vial. This helps prevent contamination and ensures accurate dosing.

Choice A rationale
A urinary tract infection (UTI) is a common cause of dark amber, cloudy urine with an unpleasant odor. UTIs are caused by bacteria that infect the urinary tract, leading to inflammation and the presence of pus or white blood cells in the urine. This can result in cloudy urine with a strong odor. Prompt treatment with antibiotics is necessary to resolve the infection and prevent complications.
Choice B rationale
Dehydration can cause dark amber urine, but it does not typically cause cloudiness or an unpleasant odor. Dehydration leads to concentrated urine, which appears darker in color. However, the presence of cloudiness and odor suggests an infection rather than dehydration.
Choice C rationale
Kidney stones can cause dark urine if there is bleeding, but they do not typically cause cloudiness or an unpleasant odor. The passage of a kidney stone can lead to hematuria (blood in the urine), which may darken the urine. However, the symptoms described are more indicative of a urinary tract infection.
Choice D rationale
Liver disease can cause dark urine due to the presence of bilirubin, but it does not typically cause cloudiness or an unpleasant odor. Dark urine in liver disease is usually accompanied by other symptoms such as jaundice, pale stools, and fatigue. The combination of dark, cloudy urine with an unpleasant odor is more suggestive of a urinary tract infection. .
