A client is receiving IV heparin and oral warfarin after a pulmonary embolism (PE). The nurse determines the client's activated partial prothromboplastin time (APTT) value is two times the control value; the prothrombin time (PT) level is the same as the control, and the international normalized ratio (INR) is 1. Which protocol prescription should the nurse implement?
Reference Range:
Activated Partial Prothromboplastin Time (APTT) [Anticoagulant therapy: 1.5 to 2 times the control value in seconds.] Prothromboplastin Time (PT) [Anticoagulant therapy: greater than 1.5 to 2 times the control value.] International Normalized Ratio (INR) [0.8 to 1.1]
Increase the warfarin dose.
Withhold the heparin and continue the same dose of warfarin.
Decrease the heparin dose.
D Increase the heparin dose and decrease the warfarin dose.
The Correct Answer is B
A) Incorrect - The APTT value being two times the control value indicates that the client's anticoagulation is within the therapeutic range. There is no need to increase the warfarin dose.
B) Correct - With the APTT value within the target range and the PT and INR values also normal, the nurse should continue the same dose of warfarin and withhold the heparin.
C) Incorrect - Decreasing the heparin dose is not indicated, as the client's APTT is already within the therapeutic range.
D) Incorrect - Increasing the heparin dose and decreasing the warfarin dose is not necessary, as the client's anticoagulation levels are appropriate.

Correct Answer is C
Explanation
A) Incorrect- an audible voice when client is trying to communicate, indicates that the client has some air passing through the vocal cords, which may be due to a partially deflated cuff or a speaking valve. This is not a life-threatening situation, but the nurse should ensure that the cuff pressure is adequate and that the client is not experiencing any discomfort or aspiration risk.
B) Incorrect- This may indicate atelectasis, pneumonia, or pleural effusion in that lung area. The nurse should auscultate the client's lungs more thoroughly, monitor the client's oxygenation and ventilation parameters, and report the findings to the provider.
C) Correct- This finding suggests that the client may have a ventilator disconnect, a leak in the circuit, or a cuff leak, which can compromise the client's oxygenation and ventilation. The nurse should immediately check the ventilator connections and tubing, and assess the client's vital signs and oxygen saturation.
D) Incorrect- high-pressure alarm sounds when the client is coughing, which is a common occurrence in mechanically ventilated clients who have increased airway resistance due to secretions, bronchospasm, or coughing. The nurse should suction the client as needed, administer bronchodilators if prescribed, and ensure that the ventilator settings are appropriate for the client's condition.
Correct Answer is A
Explanation
A) Correct - Acute dystonic reactions are involuntary muscle spasms caused by certain medications, including antipsychotic drugs. These reactions can sometimes affect the muscles of the face and neck, including the larynx. Benztropine is an anticholinergic medication commonly used to treat acute dystonic reactions. It works by blocking certain neurotransmitters that contribute to muscle spasms, helping to relieve the symptoms.
B) Incorrect - Divalproex is an anticonvulsant medication primarily used to treat epilepsy and bipolar disorder. It is not the appropriate treatment for acute dystonic reactions. These reactions are usually caused by certain antipsychotic medications and are characterized by sudden and involuntary muscle contractions. Divalproex does not have the specific mechanism of action needed to alleviate the symptoms of acute dystonic reactions.
C) Incorrect - Isotonic crystalloid fluids are used for various purposes, such as fluid resuscitation, maintaining hydration, and balancing electrolytes. However, they are not a treatment for acute dystonic reactions. These reactions are neurological and musculoskeletal in nature and require medications with specific anticholinergic properties, like benztropine, to address the underlying issue.
D) Incorrect - Lorazepam is a benzodiazepine commonly used for anxiety, sedation, and seizure control. While it can have a relaxing effect on muscles, it is not the first-line treatment for acute dystonic reactions. Anticholinergic medications like benztropine are more appropriate because they directly counteract the neurotransmitter imbalances that lead to muscle spasms in these reactions.
