A client who had a knee replacement surgery and received a prescription for enoxaparin 30 mg subcutaneously every 12 hours for 10 days. The medication is available in 30 mg per 0.3 mL pre-filled syringes. How many mL should the practical nurse (PN) administer each day? (Enter numerical value only.)

Rationale:

A: Obtain the latex free cart is incorrect. There is no evidence that the client has a latex allergy or that latex exposure triggered the malignant hyperthermia reaction.

B: Paralytic ileus is incorrect. Paralytic ileus is not the primary condition that the client is experiencing, but a possible secondary complication of malignant hyperthermia.

C: Nausea and vomiting is incorrect. Nausea and vomiting are common postoperative symptoms that may or may not be related to malignant hyperthermia.

D:Malignant hyperthermia (MH) itself does not inherently include hypercapnia as a defining characteristic. However, during an episode of malignant hyperthermia, metabolic acidosis can occur due to the increased production of lactic acid and carbon dioxide as byproducts of the hypermetabolic state. This acidosis can potentially lead to respiratory compensation mechanisms, such as increased respiratory rate and depth, to attempt to eliminate excess carbon dioxide from the body. In some cases, if the compensatory respiratory efforts are insufficient to adequately remove carbon dioxide, hypercapnia can develop as a secondary complication of malignant hyperthermia.

E: nasogastric (NG) tube is incorrect. An NG tube may be indicated for paralytic ileus or bowel obstruction, but not for malignant hyperthermia.

- F: Malignant hyperthermia is correct. The client's vital signs indicate a possible malignant hypertermia reaction, which is a rare but life-threatening complication of general anesthesia that causes a rapid rise in body temperature, muscle rigidity, tachycardia, tachypnea, and hypoxia.

- G: Administer ondansetron is incorrect. Ondansetron is an antiemetic medication that can help with nausea and vomiting, but it does not address the underlying cause of malignant hyperthermia.

- H: Administer dantrolene is correct. Dantrolene is the antidote for malignant hyperthermia and should be given as soon as possible to stop the metabolic crisis and lower the body temperature.

- I: Latex allergy is incorrect. Latex allergy is a hypersensitivity reaction to latex products that can cause urticaria, angioedema, bronchospasm, or anaphylaxis. There is no evidence that the client has a latex allergy or that latex exposure triggered the malignant hyperthermia reaction.

- J: Urticaria is incorrect. Urticaria is a skin rash that can be caused by allergic reactions, infections, or other factors. There is no evidence that the client has urticaria or that it is related to malignant hyperthermia.

- K: Muscle rigidity is correct. Muscle rigidity is one of the signs of malignant hyperthermia and should be monitored closely by the nurse.

- L: Bowel sounds is correct. Bowel sounds should be assessed regularly by the nurse to detect any signs of paralytic ileus, which is a potential complication of malignant hyperthermia that causes intestinal obstruction and abdominal distension.

A. Palpate the degree of edema. This is incorrect because palpating the degree of edema requires clinical judgment and skill, which are beyond the scope of practice of an AP.

B. Regulate IV pump fluid rate. This is incorrect because regulating IV pump fluid rate is a nursing responsibility that involves calculating and adjusting the infusion rate based on the client's condition and orders.

C. Measure the client's daily weight. This is correct because measuring the client's daily weight is a routine task that can be delegated to an AP, as long as the nurse provides clear instructions and monitors the results. The client's daily weight is an indicator of fluid balance and can help evaluate the effectiveness of treatment.

D. Assess the client's vital signs. This is incorrect because assessing the client's vital signs requires interpretation and analysis of data, which are nursing functions that cannot be delegated to an AP.
