Correct Answer: D

Rationale: The parathyroid glands regulate calcium, vitamin D, and phosphorus in the body. Hyperparathyroidism leads to excessive production of parathyroid hormone, causing the release of calcium from bones into the bloodstream, resulting in elevated blood calcium levels, known as hypercalcemia. This puts individuals at risk of developing complications such as kidney stones, bone pain, osteoporosis, and neuropsychiatric symptoms. The other options, hyponatremia, hypocalcemia, and hypermagnesemia, are not directly associated with hyperparathyroidism. Hyponatremia is low sodium levels in the blood, hypocalcemia is low calcium levels, and hypermagnesemia is high magnesium levels, which are not typically seen in hyperparathyroidism.

Correct Answer: C

Rationale: Type 1 diabetes is an autoimmune condition where the immune system attacks and destroys the beta cells in the pancreas, leading to a lack of insulin production. Insulin is essential for regulating blood glucose levels and enabling cells to use glucose for energy. Understanding that type 1 diabetes results from the destruction of beta cells helps patients comprehend the need for insulin replacement therapy. Choices A and B are incorrect as type 1 diabetes is not primarily caused by diet or exercise habits. Choice D is incorrect because type 1 diabetes is not about the body's cells rejecting insulin but rather the lack of insulin production due to beta cell destruction.

Correct Answer: B

Rationale: A lumbar puncture is performed to obtain cerebrospinal fluid for analysis to investigate various conditions affecting the client. During the procedure, the client is typically positioned on their side or sitting leaning over a table with their back rounded. The physician inserts a needle into the back around the L4-L5 vertebrae to collect the sample. Option A is incorrect because a lumbar puncture does not draw blood but instead collects cerebrospinal fluid. Option C is incorrect as the client should not necessarily lie flat for 24 hours post-procedure. Option D is incorrect as the common risks of a lumbar puncture include headache, back pain, and potential infection, not nausea, rash, or hypotension.

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: D

Rationale: When assessing blood pressure by palpation, it is important to note that only the systolic blood pressure can be determined accurately using this method. Diastolic blood pressure cannot be reliably assessed through palpation. The palpation technique is particularly useful in situations where traditional blood pressure measurement methods are challenging, such as in infants, small children, or individuals with low blood pressure that is difficult to hear. Hypertension, a common condition characterized by elevated blood pressure, is typically assessed using auscultation rather than palpation. Therefore, the correct statement is that only the systolic blood pressure can be assessed through palpation.
