Correct Answer: B

Rationale: The presentation of a patient with diabetes mellitus showing symptoms of polyuria, polydipsia, nocturia, and fatigue along with laboratory findings of hyperglycemia, glycosuria, and ketonuria is indicative of diabetic ketoacidosis (DKA). DKA is a serious complication of diabetes characterized by hyperglycemia, metabolic acidosis, and ketosis. The increased glucose levels lead to glycosuria, causing osmotic diuresis resulting in polyuria, polydipsia, and nocturia. The body starts breaking down fats for energy in the absence of sufficient insulin, leading to the production of ketones causing ketonuria. The patient may also experience fatigue due to the metabolic abnormalities present in DKA.

Correct Answer: A

Rationale: Battery refers to the intentional and offensive physical contact with another person without their consent, resulting in harm or injury. In this scenario, the victim clearly expressed their unwillingness to be touched or helped by saying, "Don't touch me!" multiple times. By ignoring the victim's refusal and physically forcing them into the ambulance, the EMT is committing battery even though they may have had good intentions to provide assistance. It is important for medical professionals, including EMTs, to always respect a person's right to refuse medical treatment or assistance, even in emergency situations.

Correct Answer: A

Rationale: The nurse should prioritize ensuring proper zeroing and calibration of the ICP monitoring system to ensure procedural accuracy and reliability of the measurements obtained. Proper zeroing involves setting the transducer at the level of the patient's external auditory meatus (ear), which serves as a reference point for accurate ICP readings. Calibration is necessary to establish accurate pressure measurements. Incorrect zeroing or calibration can lead to inaccurate ICP readings, which can impact clinical decision-making for patients with traumatic brain injury. Positioning the patient in a high-Fowler's position, administering prophylactic antibiotics, or placing the ICP monitor in the subarachnoid space via lumbar puncture are not directly related to ensuring the accuracy of the ICP monitoring procedure.

Correct Answer: A

Rationale: Sherry is a type of fortified wine produced in Spain. It is not associated with the development of hyperkalemia, which is a condition characterized by high levels of potassium in the blood. Hyperkalemia is commonly caused by kidney dysfunction, certain medications, or excessive intake of potassium-rich foods. Drinking Sherry is not likely to cause hyperkalemia. On the other hand, Sherry consumption can potentially contribute to tooth decay, gastric ulcers, and rectal bleeding due to its acidity and alcohol content.

Correct Answer: D

Rationale: Pemoline (Cylert) is a central nervous system stimulant used in the treatment of ADHD. One of the significant potential side effects of pemoline is hepatotoxicity, which can manifest as elevated liver function test results. Therefore, the nurse must monitor the patient's liver function regularly while they are taking pemoline to monitor for any signs of liver damage or dysfunction. It is essential to educate the patient about the signs and symptoms of liver problems, such as jaundice (yellowing of the skin or eyes), abdominal pain, nausea, or dark urine, and to report any such symptoms immediately to their healthcare provider. Regular monitoring and early detection of liver function abnormalities can help prevent severe liver damage in patients taking pemoline.
