A nurse is caring for a client who is scheduled to receive heparin 3,800 units subcutaneously. Available is heparin 5,000 units/mL How many ml. should the nurse administer? (Round the answer to the nearest tenth.)

A. A 19 year old with severe headache: A severe headache can indicate a variety of conditions, including migraines, tension headaches, or neurological issues, but it is not typically associated with hypovolemic shock which results from significant fluid loss.

B. A 38 year old with a urinary tract infection: A urinary tract infection (UTI) does not usually lead to hypovolemic shock unless there is sepsis or severe dehydration. UTIs primarily cause urinary symptoms and fever, not hypovolemic shock.

C. A 20 year old with fibromyalgia: Fibromyalgia is a chronic pain condition that causes widespread musculoskeletal pain and fatigue. It does not typically lead to hypovolemic shock, which is a result of significant fluid or blood loss.

D. A 66 year old in diabetic ketoacidosis (DKA): DKA can lead to hypovolemic shock due to significant fluid loss from dehydration and electrolyte imbalances. In DKA, excessive urination and hyperglycemia lead to dehydration, making this client at risk for hypovolemic shock.

A. Insert a padded tongue blade into the client's mouth: Inserting a tongue blade can cause harm, such as damaging the client's teeth or mouth or causing them to bite down on the blade, leading to injury. It is not recommended during a seizure.

B. Place a pillow under the client's head: Placing a pillow under the client’s head helps protect it from injury during the clonic phase of a seizure. This is the most appropriate and safest action to prevent head trauma while the client is experiencing a seizure.

C. Gently restrain the client's extremities: Restraint during a seizure can lead to injury and should be avoided. The priority is to allow the seizure to occur without interference, ensuring the client’s safety by preventing injury from the environment.

D. Apply a face mask for oxygen administration: Oxygen may be indicated if the client shows signs of respiratory distress, but applying a face mask immediately is not the priority. Ensuring safety during the seizure (e.g., protecting the head) is more important in the initial response.
