A client receives a prescription for dextrose 5% in water 500 mL IV to be infused over 4 hours. The IV administration set delivers 15 gtt/mL. How many gtt/min should the nurse regulate the infusion? (Enter numerical value only. If rounding is required, round to the nearest whole number.)

A) Request a prescription to change the route of administration and use the available heparin:
Changing the route of administration without a prescription is not within the nurse's scope of practice and could lead to medication errors or adverse effects. It's essential to follow the prescribed route of administration to ensure patient safety.

B) Calculate and administer the equivalent dose of the available low molecular weight heparin:
Low molecular weight heparin (LMWH) has different dosing and potency compared to unfractionated heparin. Calculating an equivalent dose without a specific conversion ratio could result in under- or overdosing, leading to ineffective anticoagulation or increased risk of bleeding.

C) Advise the pharmacy of the need to deliver a vial of heparin to the nursing unit immediately:
This is the correct action. Since the prescription specifies unfractionated heparin administered intravenously, the nurse should notify the pharmacy to provide the correct medication promptly. Using a different form of heparin could lead to dosing errors or ineffective treatment.

D) Dilute the available heparin in 250 mL of normal saline solution prior to IV administration:
This action is not appropriate because it assumes that the available heparin is suitable for intravenous administration, which may not be the case. Dilution may also alter the concentration and potency of the medication, leading to inaccurate dosing and potential adverse effects.

A) Platelets:
Platelet levels are not directly affected by antidiuretic hormone (ADH) administration or diabetes insipidus. Platelet monitoring is important in assessing clotting function but is not specifically related to the management of diabetes insipidus or ADH therapy.

B) Osmolality:
This is the correct answer. Osmolality refers to the concentration of solutes in the blood and is a critical parameter to monitor in clients receiving ADH therapy for diabetes insipidus. ADH regulates water reabsorption in the kidneys, thereby affecting blood osmolality. Monitoring serum osmolality helps assess the effectiveness of ADH therapy in maintaining fluid balance and preventing excessive urine output.

C) Glucose:
While glucose monitoring is important in clients with diabetes mellitus, it is not directly related to diabetes insipidus or ADH therapy. Diabetes insipidus is characterized by excessive thirst and urination due to inadequate ADH production or response, which does not involve glucose metabolism.

D) Calcium:
Calcium levels are not typically affected by ADH therapy or diabetes insipidus. Monitoring calcium levels is important in conditions such as hyperparathyroidism or hypoparathyroidism but is not directly relevant to the management of diabetes insipidus.
