A nurse caring for a client with hypocalcemia would expect to note which of the following changes on the electrocardiogram?

Correct Answer: C

Rationale: In hypocalcemia, a decreased level of calcium can lead to a prolonged QT interval on the ECG due to its role in myocardial repolarization. A widened T wave (Choice A) is typically seen in hyperkalemia. A prominent U wave (Choice B) is associated with hypokalemia. A shortened ST segment (Choice D) is not a typical ECG finding in hypocalcemia.

Correct Answer: C

Rationale: The correct answer is C: 'Monitoring.' Monitoring involves regularly checking and observing the status of a unit or situation. In this scenario, the nurse manager is actively seeking feedback from staff members to assess and keep track of the staffing situation. Choice A, 'Spokesperson,' refers to a role where someone represents or speaks on behalf of a group or organization, which is not the primary activity in this case. Choice B, 'Reporting,' typically involves presenting information or data about a specific topic or issue but does not capture the ongoing observation and assessment aspect seen in monitoring. Choice D, 'Job analysis and redesign,' involves assessing and restructuring job roles, responsibilities, and tasks, which is not directly related to the action of monitoring staffing levels.

Correct Answer: C

Rationale: A blood pH of 7.25 is a critical finding in diabetic ketoacidosis (DKA) as it indicates metabolic acidosis, which is a hallmark of this condition. In DKA, there is an accumulation of ketones in the blood, leading to increased acidity. The serum glucose level is typically elevated in DKA, often exceeding 250 mg/dL. A serum bicarbonate level less than 18 mEq/L is usually seen in DKA due to the metabolic acidosis. Urine specific gravity is not a specific indicator for DKA and may vary depending on the individual's hydration status. Therefore, the correct lab finding that confirms DKA in this scenario is a blood pH of 7.25.

Correct Answer: C

Rationale: Propranolol is a beta-blocker commonly used in the management of hyperthyroidism. It works by blocking the effects of adrenaline, resulting in a decrease in heart rate and blood pressure. Choice A is incorrect because propranolol does not increase metabolism; instead, it may have a mild inhibitory effect. Choice B is incorrect as propranolol is not primarily used to reduce anxiety, although it may have some anxiolytic effects. Choice D is incorrect as propranolol actually decreases blood pressure by blocking the effects of adrenaline on the heart and blood vessels.

Correct Answer: C

Rationale: The correct answer is to increase physical activity to help control blood glucose levels. Physical activity is essential in managing type 2 diabetes mellitus as it helps improve insulin sensitivity, control weight, and regulate blood sugar levels. Avoiding all forms of physical exercise (Choice A) is incorrect as exercise plays a crucial role in diabetes management. While limiting carbohydrate intake (Choice B) can be beneficial, setting a strict limit of less than 30 grams per day is too restrictive and may not be suitable for everyone. Consuming a high-protein, low-fat diet (Choice D) is generally a healthy choice, but it is not the primary lifestyle modification recommended for managing type 2 diabetes mellitus.

Correct Answer: B

Rationale: In hyperparathyroidism, there is an overproduction of parathyroid hormone, leading to increased calcium levels in the blood (hypercalcemia). This occurs as the parathyroid hormone stimulates the release of calcium from the bones and enhances calcium absorption in the intestines and kidneys. Therefore, the correct answer is hypercalcemia (Choice B). Hypocalcemia (Choice A) is not consistent with hyperparathyroidism, as this condition is characterized by high calcium levels. Hypokalemia (Choice C) and hyperphosphatemia (Choice D) are not typically associated with hyperparathyroidism and are not primary manifestations of this condition.

Correct Answer: B

Rationale: A client with hyperparathyroidism is at risk for osteoporosis, not hypocalcemia, hypokalemia, or hyponatremia. Hyperparathyroidism results in increased levels of parathyroid hormone, which causes excessive breakdown of bone tissue to release calcium into the bloodstream. This process can lead to weakened bones and an increased risk of osteoporosis. Hypocalcemia is unlikely in hyperparathyroidism as the condition is characterized by elevated calcium levels due to the abnormal activity of the parathyroid glands. Hypokalemia and hyponatremia are not directly associated with hyperparathyroidism; they are more commonly linked to other conditions affecting potassium and sodium levels in the body.

Correct Answer: B

Rationale: The correct answer is B. Acarbose (Precose) is an alpha-glucosidase inhibitor that works by slowing carbohydrate absorption in the intestine, not by stimulating insulin release. Therefore, the client would need additional teaching if they state that the drug makes their pancreas release more insulin (Choice B). Choices A, C, and D are incorrect. Choice A is incorrect because during hypoglycemia, it is recommended to consume glucose or dextrose to rapidly raise blood sugar levels. Choice C is incorrect because insulin therapy may still be needed in some cases, even when taking acarbose. Choice D is incorrect because acarbose should be taken at the start of a meal to help reduce postprandial blood glucose levels.

Correct Answer: C

Rationale: The correct instruction is choice C: 'You may not be able to use desmopressin nasally if you have nasal discharge or blockage.' Nasal congestion or blockage can interfere with the absorption of nasally administered desmopressin. Choices A, B, and D are incorrect. Choice A is unnecessary as the temperature of the suspension does not impact desmopressin administration. Choice B is incorrect as wearing a medical identification bracelet is essential for individuals with diabetes insipidus to alert healthcare providers in case of emergencies. Choice D is incorrect as monitoring fluid intake and output is crucial when taking desmopressin to ensure proper hydration and medication effectiveness.
