A client is on intravenous heparin to treat DVT in the right leg. The client’s most recent partial thromboplastin time (PTT) was 25 seconds. What order would the nurse anticipate?

No change to the heparin rate

Decrease the heparin rate

Stop heparin and start warfarin

Increase the heparin rate

Answer and Explanation

The Correct Answer is D

Choice A reason: No change to the heparin rate is not appropriate in this scenario. The normal range for PTT is generally between 25 to 35 seconds. However, for a client on heparin therapy, the target PTT is typically 1.5 to 2.5 times the normal range, which would be approximately 60 to 80 seconds. Since the client’s PTT is only 25 seconds, it indicates that the blood is clotting too quickly, and the heparin dose is insufficient.

Choice B reason: Decreasing the heparin rate would further reduce the anticoagulant effect, which is not advisable given the current PTT of 25 seconds. Lowering the heparin rate could increase the risk of thrombus formation and worsen the deep vein thrombosis (DVT) condition.

Choice C reason: Stopping heparin and starting warfarin is not an immediate solution. Warfarin takes several days to achieve its full anticoagulant effect, and during this transition period, the client would be at risk of clot formation. Heparin provides immediate anticoagulation, which is crucial in the acute management of DVT.

Choice D reason: Increasing the heparin rate is the correct action. The current PTT of 25 seconds is below the therapeutic range for a client on heparin therapy. Increasing the heparin rate will help achieve the desired anticoagulant effect, prolonging the PTT to the target range of 60 to 80 seconds.

Correct Answer is A

Explanation

Choice A Reason:

Hemoptysis, or coughing up blood, is a common feature of both mitral valve stenosis and mitral valve regurgitation. In mitral valve stenosis, the narrowing of the valve leads to increased pressure in the pulmonary veins, which can cause pulmonary congestion and hemoptysis. Similarly, in mitral valve regurgitation, the backflow of blood into the left atrium increases pulmonary pressure, potentially leading to pulmonary edema and hemoptysis. Therefore, hemoptysis is a shared symptom of both conditions.

Choice B Reason:

A high-pitched holosystolic murmur is more commonly associated with mitral valve regurgitation rather than mitral valve stenosis. In mitral valve regurgitation, the murmur is caused by the backflow of blood from the left ventricle into the left atrium during systole3. Mitral valve stenosis, on the other hand, typically presents with a diastolic murmur due to the turbulent flow of blood through the narrowed valve during diastole. Therefore, a high-pitched holosystolic murmur is not a common feature of both disorders.

Choice C Reason:

Hepatomegaly, or an enlarged liver, can occur in advanced cases of both mitral valve stenosis and mitral valve regurgitation due to right-sided heart failure. However, it is not a primary or common feature of these conditions. Hepatomegaly is more often associated with conditions that directly affect the right side of the heart or cause systemic congestion. Therefore, hepatomegaly is not a common feature of both mitral valve stenosis and mitral valve regurgitation.

A. Lean on your back with your knees bent. B. Use your abdominal muscles to squeeze air out of your lungs. C. Breathe out slowly without puffing your cheeks. D. Focus on inhaling and holding your breath as long as you can. E. Exhale at least twice the amount of time it took to breathe in. F. Open your mouth and breathe deeply.

Correct Answer is ["B","C","E"]

Explanation

Choice A: Lean on your back with your knees bent.

Reason: This instruction is incorrect. Pursed lip breathing is typically performed in a seated position with the neck and shoulders relaxed. Lying on your back with knees bent is not a recommended position for this breathing technique.

Choice B: Use your abdominal muscles to squeeze air out of your lungs.

Reason: This instruction is correct. Using the abdominal muscles helps to expel air more effectively from the lungs, which is a key component of pursed lip breathing. This technique helps to improve ventilation and reduce the work of breathing.

Choice C: Breathe out slowly without puffing your cheeks.

Reason: This instruction is correct. Breathing out slowly through pursed lips without puffing the cheeks helps to keep the airways open longer, allowing more air to be expelled from the lungs. This technique is particularly beneficial for individuals with chronic obstructive pulmonary disease (COPD) or other respiratory conditions.

Choice D: Focus on inhaling and holding your breath as long as you can.

Reason: This instruction is incorrect. The focus of pursed lip breathing is on controlled exhalation rather than holding the breath. Inhaling should be done slowly through the nose, and exhaling should be prolonged through pursed lips.

Choice E: Exhale at least twice the amount of time it took to breathe in.

Reason: This instruction is correct. The exhalation phase should be longer than the inhalation phase, typically taking at least twice as long. This helps to improve the efficiency of breathing and reduce shortness of breath.

Choice F: Open your mouth and breathe deeply.

Reason: This instruction is incorrect. Pursed lip breathing involves breathing in through the nose and exhaling through pursed lips. Opening the mouth and breathing deeply is not part of this technique.
