Correct Answer: D

Rationale: A hemoglobin A1C test, also known as a glycated hemoglobin test, determines the amount of hemoglobin that is coated with glucose. Excess glucose in the bloodstream may cause it to attach to hemoglobin on red blood cells. Because the life of these cells is between 2 and 3 months, the hemoglobin A1C is an accurate measurement of a client's glucose during that time. Choices A, B, and C are incorrect. Choice A relates to anemia and iron supplements, which are not assessed by a hemoglobin A1C test. Choice B mentions excess glucose in the urine, which is typically assessed through a urine glucose test, not the hemoglobin A1C test. Choice C is incorrect as the test is not related to the amount of hemoglobin reaching the liver to support gluconeogenesis; instead, it specifically measures the amount of hemoglobin that is glycated or coated with glucose.

Correct Answer: B

Rationale: When preparing to give a stool sample for occult blood testing, clients need specific instructions to ensure accurate results. It is crucial to educate clients to avoid eating red meat for at least 3 days before the test, as the blood in the meat can interfere with the test results. Clients should be informed that the stool does not need to be kept in a container with preservative as it is not required for this type of testing. Additionally, clients should be aware that a small part of the stool from two areas will be tested using a smear. However, collecting the stool sample from the toilet after having a bowel movement is not recommended as it may introduce contaminants and affect the accuracy of the test. Therefore, this information is not part of the correct teaching for the client preparing to give a stool sample for occult blood.

Correct Answer: D

Rationale: A client with a blood glucose level of 48 mg/dl is experiencing significant hypoglycemia, as manifested by confusion, balance difficulties, and slurred speech. The nurse should work to correct this situation as rapidly as possible. The first measure that can be performed quickly and will have fast results is to give the client something to eat or drink that contains glucose, such as 6 oz. of orange juice. Administering a bolus of D20W through the IV (Choice B) would be too aggressive and could lead to complications in this scenario. Administering regular insulin (Choice C) would further lower the blood glucose level, worsening the client's symptoms. Contacting the physician (Choice A) is important, but immediate intervention to raise the blood glucose level is crucial to address the client's hypoglycemia.

Correct Answer: A

Rationale: Mr. N is exhibiting Kussmaul respirations, characterized by rapid, deep, and regular breathing. This type of respiratory pattern is commonly seen in metabolic acidosis, such as in diabetic ketoacidosis. Kussmaul respirations are a form of hyperventilation, leading to the elimination of carbon dioxide from the body. Choice B, Cheyne-Stokes respirations, is characterized by alternating periods of deep, rapid breathing followed by periods of apnea and is not typically associated with diabetic ketoacidosis. Choice C, Biot's respirations, involve irregular breathing patterns with periods of apnea and are not reflective of the described breathing pattern. Cluster breathing, as mentioned in Choice D, is not a recognized term in respiratory patterns and does not describe the breathing pattern observed in Mr. N.

Correct Answer: B

Rationale: Heat exhaustion occurs when a person has enough diaphoresis that he becomes dehydrated. Intense sweating can cause both luid and electrolyte imbalances. Untreated heat exhaustion can lead to heat stroke, which results in organ damage, loss of consciousness, or death.
