Loop diuretics such as Lasix result in potent diuresis.  The most common side effects are electrolyte imbalances such as hypokalemia, hyponatremia making choices (1), (2) and (4) incorrect.  In addition, Digoxin taken in combination with loop diuretics can result in digitalis toxicity, so the nurse should be alert to this and normal serum lab values for Digoxin (Norm:  0.5-2.0 ng/ml).  The nurse should be aware that there is a very small variance between therapeutic and toxic levels of this drug. 2. D. A patient in 3 degree A-V Block has all sinus impulses blocked and abnormal ventricular conduction, as well as a heart rate of 40-60 bpm or less and will therefore need support in the form of a pacemaker and/or use of meds such as atropine or Isoproterenol (Isuprel).  Choice (2) Digoxin, a cardiac glycoside would only further decrease heart rate; Choice (3) Lidocaine is used in treatment of PVC’s; Choice (4) may seem a possible option, however, with proper medical management a heart rate sufficient to support perfusion can be maintained making CPR unnecessary. 3. C. A client should NOT repeat a dose if first dose is vomited, as one would not know how much of the original dose was absorbed, and could possibly lead to excess Digoxin levels, which can cause arrhythmias, or slow heart rate below 60 bpm.  Choices...

Increase specific gravity of urine b. Hyperkalemia c. Hypokalemia d. Hypernatremia 2. You are caring for a client just diagnosed with 3 degree A-V Block.  Which of the following should the nurse be prepared to do? a. Assist in possible insertion of a pacemaker b. Administer Digoxin c. Administer Lidocaine d. Assist in doing CPR 3. A client is discharged on Digoxin (Lanoxin) following hospitalization for Atrial Fibrillation.  In preparing a Discharge Teaching Plan, the nurse would NOT include which of the following? a. Take pulse correctly and count for one full minute b. Report any signs and/or symptoms such as ocular disturbances, anorexia, etc.,  to M.D. promptly c. Take another dose of medication if first dose is vomited d. Withhold drug if heart rate falls below 60 bpm 4. A mother calls the clinic and asks to speak to the nurse regarding her 6 month old daughter who has been vomiting for the past 24 hours.  The mother states that the baby is on Digoxin for a congenital heart defect and she is concerned that this may be a serious problem.  What instructions should...

This patient is suffering from frostbite, due to prolonged exposure to sub-freezing temperatures without proper protection.  Frostbite is a condition in which there is trauma to the tissues without actual freezing of tissue fluids.  Exposed areas of the body such as hands, feet, earlobes, etc. are all subject to this.  The affected part becomes hard, cold, and is not sensitive to touch, and mottled bluish-white in color. The aim of nursing care is to restore normal temperature and circulation to the part.  All other choices would be included in the management of such a patient.   Choice (2) is incorrect in that wrapping of the part could further constrict circulation.  If blankets are used, it should be supported with a foot cradle and not in direct contact with the extremity.  Prolonged applications of heat should also be avoided due to the patient’s diminished sensitivity, and could result in a burn if not carefully monitored. 2. A. If the hip if flexed to the side, on the side of the bed or in a low chair, hip displacment can occur. Displacement could result in pain, but this is not the primary reason for the instructions. The remaining two answers are not specific or adequate explanations. 3. A. Abnormal discoloration of the scrotal area following Vasectomy is not unusual, and usually responds well to warm sitz baths.  The...

It’s Free. 1. A homeless individual is brought to the Emergency Room after having been out in subfreezing temperatures for three to four days. The toes of the patient’s right foot appear hard and cold with mottling, and are unresponsive to touch.  Which of the following would NOT be included in the initial management of this patient by the Emergency Room nurse: a. Rewarm the extremity with controlled and rapid rewarming until the injured part flushes b. Wrap the affected extremity in a blanket and apply moist heat c. Place sterile gauze between the affected digits d. Elevate the affected extremity 2. An elderly client has sustained an intertrochanteric fracture of the hip and has just returned from surgery where a nailplate was inserted for internal fixation. The client has been instructed that she should not flex her hip. The best explanation of why this movement would be harmful is a. Displacement can occur with flexion. b. The soft tissue around the site will be damaged. c. It will be very painful for the client. d. It will pull the hip out of alignment. 3. Following a Vasectomy, a patient notices discoloration of the scrotal area and becomes alarmed.  In responding to the patient’s concern the nurse should:  a. Explain to the patient that this is a normal finding and...

D.  Clients should understand it is important to increase their fluid intake to at least 2000 ml each day. The increased fluid will assist in urate excretion and minimize urate precipitation in the urinary tract. Certain meats, such as organ meats and shellfish, are high in purine and should be restricted. 2. C. It is easier for infectious agents to travel from the nasopharyngeal area to the middle ear in younger than in older children because the eustachian tube is straighter when they are younger. 3. B. The test is done primarily to determine fetal trisomy 21 (Down’s syndrome) in pregnant women over 35 years of age. If the fetus is defective and the woman or couple do not wish to have an elective abortion, the procedure would probably not be performed due to its potential risk (though small) to the woman. Answer (C) is not correct as Ashkenazic Jews have a high incidence of Tay-Sachs disease. Although more difficult, amniocentesis may be performed on women carrying twins. 4. A. Liquids are not started until bowel sounds have returned; if there is no motility in the bowel, blockage could result. Clear liquid diets are started as soon as bowel sounds return. Diet protocol following major surgery begins with clear liquid to full liquid to soft to regular diet as tolerated. 5. A. Weights must...
