The nurse is caring for a client following a coronary artery bypass graft (CABG). The nurse notes persistent oozing of bloody drainage from various puncture sites. The nurse anticipates that the physician will order which medication to neutralize the unfractionated heparin the client received?

The sinoatrial (SA) node initiates the impulse.

A home health nurse is seeing an elderly male client for the first time. During the physical assessment of the skin on the lower legs, the nurse notes edema, brown pigmentation in the gaiter area, pedal pulses, and a few irregularly shaped ulcers around the ankles.

left lateral

Administer epinephrine.

A client has sustained a right tibial fracture and has just had a cast applied. Which instruction should the nurse provide concerning cast care?

"Keep your right leg elevated above heart level."

The nursing student asks the nurse to describe the difference between sinus rhythm and sinus bradycardia on the electrocardiogram strip. What is the nurse's best reply?

"The only difference is the heart rate."

The nurse knows that the main objective of the management of hypertension is to achieve a sustainable level of blood pressure below:

140/90

A client is hospitalized 3 days prior to a total hip arthroplasty and reports a high level of pain with ambulation. The client has been taking warfarin at home, which is now discontinued. To prevent the formation of blood clots, which action should the nurse take?

Blood has accumulated between the man's dura and subarachnoid space.

A client with inflammatory bowel disease undergoes an ileostomy. On the first day after surgery, the nurse notes that the client's stoma appears dusky. How should the nurse interpret this finding?

Blood supply to the stoma has been interrupted.

Which is a key diagnostic indicator of heart failure?

Brain natriuretic peptide (BNP)

A client had a percutaneous transluminal coronary angioplasty (PTCA). What medication will the nurse administer to prevent thrombus formation in the stent?

Clopidogrel

The nurse provides care for a client with a full-thickness, circumferential burn of the left lower leg. During the nurse's initial shift assessment, the client is resting and the physical assessment of the left lower extremity is unremarkable.

What is the nurse's best response based on the clinical findings?

Contact the primary care provider and prepare for an escharotomy.

The nurse is performing the history and physical examination on a client who is being admitted for anorexia nervosa. The client, a 23-year-old, is 5 feet 2 inches, and weighs 88 pounds. The nurse assesses the client's history of weight gain and loss, typical daily food intake, electrolyte and other blood studies, and elimination patterns. The nurse observes typical physical findings such as dry skin, lanugo, and brittle hair and nails. Which factor is a priority for the nurse to assess next?

Heart rate and rhythm

A client presents to the clinic with symptoms of elevated blood pressure, dizziness, red face, pain in fingers and toes, headache, and difficulty concentrating. A blood smear reveals an increased number of erythrocytes. Based on these findings, the nurse anticipates which diagnosis?

Polycythemia vera

What is the correct sequence for the generation of electrical impulses in the heart causing ventricular contraction?

SA node - AV node - bundle of His - bundle branches - Purkinje fibers

Which type of epithelium is found in the lining of blood vessels, lymph nodes, and alveoli of the lungs?

Simple squamous epithelium

Potassium is the major cation in the body. It plays many important roles, including the excitability of nerves and muscles. Where is this action particularly important?

When trying to explain to a client on dialysis the movement of substances through the capillary pores, the nurse will explain that in the kidneys, the glomerular capillaries have:

description of the pain
