Nokea
A client, experiencing a sudden onset of chest pain and dyspnea, is diagnosed with a pulmonary embolus. Which expected prescription should the nurse immediately implement for this client? Select all that apply.
- A. Supplemental oxygen
- B. High Fowler's position
- C. Semi-Fowler's position
- D. Morphine sulfate intravenously
- E. Two tablets of acetaminophen with codeine
- F. Meperidine hydrochloride intravenously
Correct Answer: A,C,D
Rationale: Standard therapeutic intervention for the client with pulmonary embolus includes proper positioning, oxygen, and intravenous analgesics. The head of the bed is placed in semi-Fowler's position. Fowler's is avoided because extreme hip flexure slows venous return from the legs and increases the risk of new thrombi. The usual analgesic of choice is morphine sulfate administered intravenously. This medication reduces pain, alleviates anxiety, and can diminish congestion of blood in the pulmonary vessels because it causes peripheral venous dilation.

The nurse caring for an infant demonstrating diarrhea should monitor the infant for which early sign of dehydration?
- A. Cool extremities
- B. Gray, mottled skin
- C. Capillary refill of 3 seconds
- D. Apical pulse rate of 200 beats per minute
Correct Answer: D
Rationale: Dehydration causes interstitial fluid to shift to the vascular compartment in an attempt to maintain fluid volume. When the body is unable to compensate for fluid lost, circulatory failure occurs. The blood pressure will decrease and the pulse rate will increase. This will be followed by peripheral symptoms.
An adolescent is hospitalized with a diagnosis of Rocky Mountain spotted fever (RMSF). The nurse anticipates that which medication will be prescribed?
- A. Ganciclovir
- B. Amantadine
- C. Doxycycline
- D. Amphotericin B
Correct Answer: C
Rationale: The nursing care of an adolescent with RMSF includes the administration of doxycycline. An alternative medication is chloramphenicol. Ganciclovir is used to treat cytomegalovirus. Amantadine is used to treat Parkinson's disease. Amphotericin B is used for fungal infections.
The nurse is developing a care plan for an older client being admitted to a long-term care facility. Which information should the nurse use to plan interventions for this client? Select all that apply.
- A. Older clients tend to be incontinent.
- B. Older clients are at risk for dehydration.
- C. Depression is a normal part of the aging process.
- D. Age-related skin changes require special monitoring.
- E. Older clients are at risk for complications of immobility.
- F. Confusion and cognitive changes are common findings in the older population.
Correct Answer: B,D,E
Rationale: Older clients are at risk for dehydration and complications related to immobility. Another normal physiological change that occurs during the aging process is loss of skin integrity. Incontinence, depression, confusion, and cognitive changes are not normal parts of the aging process.
The nurse is applying electrocardiogram (ECG) electrodes to a diaphoretic client. Which intervention should the nurse take to keep the electrodes securely in place?
- A. Secure the electrodes with adhesive tape.
- B. Place clear, transparent dressings over the electrodes.
- C. Apply lanolin to the skin before applying the electrodes.
- D. Cleanse the skin with alcohol before applying the electrodes.
Correct Answer: D
Rationale: Alcohol defats the skin and helps the electrodes adhere to the skin. Placing adhesive tape or a clear dressing over the electrodes will not help the adhesive gel of the actual electrode make better contact with the diaphoretic skin. Lanolin or any other lotion makes the skin slippery and prevents good initial adherence.
A client, admitted to the hospital for evaluation of recurrent runs of ventricular tachycardia, is scheduled for electrophysiology studies (EPS). Which statement should the nurse include in a teaching plan for this client?
- A. You will continue to take your medications until the morning of the test.
- B. You will be sedated during the procedure and will not remember what has happened.
- C. This test is a noninvasive method of determining the effectiveness of your medication regimen.
- D. The test uses a special wire to increase the heart rate and produce the irregular beats that cause your signs and symptoms.
Correct Answer: D
Rationale: The purpose of EPS is to study the heart's electrical system. During this invasive procedure, a special wire is introduced into the heart to produce dysrhythmias. To prepare for this procedure, the client should be NPO for 6 to 8 hours before the test, and all antidysrhythmics are held for at least 24 hours before the test to study the dysrhythmias without the influence of medications. Because the client's verbal responses to the rhythm changes are extremely important, sedation is avoided if possible.
