The nurse is caring for a client, the lab results are listed in the table. The nurse would anticipate the administration of which blood product(s) for this client?

Cryoprecipitate and red blood cells

Platelets and fresh frozen plasma

Packed red blood cells and platelets

Fresh frozen plasma and cryoprecipitate

Answer and Explanation

The Correct Answer is C

A.   Cryoprecipitate is indicated for low fibrinogen or clotting factor issues, but the client’s primary issue
here is anemia and thrombocytopenia.
B.   FFP is used to replace clotting factors. While it could be considered in certain situations, in this case, the primary concern is the severe anemia and thrombocytopenia.
C.   This is the most appropriate choice, as the patient has low hemoglobin (anemia) and a very low platelet count, both of which require packed red blood cells and platelets.
D.   This combination is typically used for clotting factor issues, not anemia and thrombocytopenia.

Correct Answer is B

Explanation

A. Sodium is crucial for maintaining normal cellular function, especially for nerve impulses and muscle contractions. However, sodium imbalances typically affect the general function of the heart, and sodium abnormalities are not commonly associated with torsades de pointes, which is a type of polymorphic ventricular tachycardia.
B. Magnesium plays a critical role in the electrical stability of the heart and helps regulate potassium and calcium channels, which are involved in the cardiac action potential. Hypomagnesemia (low magnesium) is a well-known risk factor for torsades de pointes, a specific type of polymorphic ventricular tachycardia that is associated with QT interval prolongation. In this case, the magnesium level is 2.5 mg/dL, which is above the normal range (1.6-2.2 mg/dL), suggesting hypermagnesemia.
C. Calcium is vital for proper muscle function, including the heart muscle, and is essential for electrical conduction. Hypocalcemia (low calcium) can lead to QT interval prolongation, which in turn increases the risk for arrhythmias such as torsades de pointes. However, in this case, the calcium level is 8.0 mg/dL, which is only slightly below the normal range (8.2-10.2 mg/dL), making calcium a less likely primary contributor to torsades de pointes in this situation.
D. Potassium plays a crucial role in regulating the resting membrane potential and action potentials in cardiac cells. Hypokalemia (low potassium) can lead to QT prolongation and increase the risk of arrhythmias, including torsades de pointes. However, in this case, the potassium level is 2.8 mEq/L, which is low (normal range: 3.5-5.3 mEq/L), and hypokalemia is more commonly associated with arrhythmias such as torsades de pointes than hyperkalemia (high potassium).

A. Petechiae B. Diarrhea C. Intractable vomiting D. Urinary incontinence

Correct Answer is A

Explanation

A. Petechiae (small, pinpoint hemorrhages) are a common manifestation of DIC due to the excessive clotting and subsequent breakdown of clotting factors, leading to bleeding into the skin.
B. Diarrhea is not typically a primary symptom of DIC, although gastrointestinal bleeding can occur in severe cases.
C. Intractable vomiting is not characteristic of DIC, although it could occur in clients with severe bleeding or complications.
D. Urinary incontinence is not a direct manifestation of DIC, although it could occur secondary to neurological or other systemic complications.

Correct Answer is B

Explanation

The nurse would assess the client diagnosed with disseminated intravascular coagulation (DIC) for which manifestation of the disorder?

Correct Answer is A

Explanation

The nurse is caring for a client who is to have an autologous transfusion of packed red blood cells. The nurse recognizes the client requires additional teaching when they state:

The nurse is caring for a client in the coronary care unit and the monitor depicts the rhythm shown below. What is the nurse’s interpretation of this rhythm?

A patient is prescribed 250 mL of packed red blood cells to be transfused over 120 minutes. The drop factor on the tubing is 15 gtt/mL. At what rate should the nurse regulate the IV (gtt/min)? (round to the nearest whole number)

The physician has just informed a client with advanced heart failure that a left ventricular assist device (LVAD) will be needed. The client is crying and says to the nurse, "I just know that I am going to die. What's the point of treatment?" The priority nursing action is to:

The nurse is planning care for a client diagnosed with heart failure who will soon be discharged home. What should be included in the teaching plan? The client will:

A patient is ordered 1 mg/kg of furosemide IV push. The patient weights 121 Ibs. The medication is supplied 40 mg/10 mL. How many mL should the nurse administer? (round to the nearest tenth)

The nurse is providing discharge instructions to a client who has had a permanent pacemaker inserted. The information in the chart indicates that the device is a DDD. What will the nurse explain about this pacemaker?

The nurse is evaluating the outcomes for a client diagnosed with disseminated intravascular coagulation (DIC). Which laboratory value reflects a positive outcome?
