A nurse is preparing to give a client an infusion of packed red blood cells (PRBCS). The nurse is priming her administration IV tubing, the nurse primes one side of the Y tubing with the blood and the other should be which solution?
DSW
0.3% NS
Lactated Ringers
0.9% NS
The Correct Answer is D
A) D5W: Dextrose 5% in water (D5W) is not used with blood transfusions because it can cause hemolysis of the red blood cells due to its hypotonic nature. It can also potentially cause clumping and clotting.
B) 0.3% NS: This is a hypotonic saline solution, which can lead to hemolysis of red blood cells when used as a diluent for blood products. It is not appropriate for use in blood transfusions.
C) Lactated Ringers: Although lactated Ringer's solution is often used for fluid resuscitation, it contains calcium, which can cause clotting in the blood product. Therefore, it is not suitable for use with blood transfusions.
D) 0.9% NS: Normal saline (0.9% sodium chloride) is isotonic and the only solution recommended for use with blood transfusions. It does not cause hemolysis of red blood cells, does not alter the composition of the blood product, and helps to maintain the patency of the IV line. It is the standard diluent used in blood transfusions to ensure the safe administration of blood products.

Correct Answer is A
Explanation
A) Speech Therapist: A speech therapist is the appropriate professional for assessing and managing dysphagia, especially in clients who have experienced a stroke. They specialize in evaluating swallowing function, determining the safest consistencies of food and liquids, and providing strategies or exercises to improve swallowing ability. They play a critical role in deciding the safest method of feeding, whether it involves modified diets or alternative feeding methods.
B) Respiratory Therapist: Respiratory therapists focus on assessing and managing respiratory conditions. While they may become involved if there are concerns about aspiration leading to respiratory complications, they do not directly manage dysphagia or feeding issues.
C) Physical Therapist: Physical therapists work primarily on improving gross motor skills, mobility, and physical function. They do not specialize in swallowing disorders or feeding methods, so they are not the primary professionals to consult for issues related to dysphagia.
D) Occupational Therapist: Occupational therapists can assist clients with fine motor skills and daily living activities, which may include feeding. However, they do not specialize in assessing or treating swallowing disorders. Their role would be more focused on helping clients with the practical aspects of self-feeding once safe swallowing methods are established by a speech therapist.
Correct Answer is D
Explanation
A) Blood pressure 178/90 mm Hg: Elevated blood pressure is more commonly associated with fluid overload or hypertension rather than dehydration. In dehydration, one would expect to see a decrease in blood pressure, particularly orthostatic hypotension, due to a reduction in blood volume.
B) Edema: Edema indicates fluid retention in the tissues, which is a sign of fluid overload rather than dehydration. Dehydration typically results in reduced extracellular fluid volume, leading to symptoms like dry mucous membranes and poor skin turgor, rather than swelling.
C) Bounding bilateral pulses: Bounding pulses are usually seen in conditions of increased cardiac output or fluid overload, where there is an excess of fluid volume. In contrast, dehydration often leads to weak and thready pulses due to decreased circulatory volume.
D) Increased urine specific gravity: Increased urine specific gravity is a direct indicator of dehydration. It occurs because the kidneys concentrate urine to conserve water, leading to a higher concentration of solutes in the urine. This is a reliable clinical marker of reduced hydration status, reflecting the body's attempt to maintain fluid balance by conserving water.
