Nokea
The nurse is caring for a client with a fracture of a long bone. Which of the following assessments would be the earliest symptom of a fat embolism?
- A. Respiratory distress.
- B. Confusion.
- C. Petechiae.
- D. Fever.
Correct Answer: A
Rationale: Respiratory distress is the earliest symptom of fat embolism syndrome, as emboli obstruct pulmonary circulation, leading to hypoxia.

The nurse is caring for a client taking memantine. Which data should the nurse monitor for this client?
- A. Liver function studies
- B. Complete blood count
- C. Renal function studies
- D. Pulmonary function studies
Correct Answer: C
Rationale: Memantine is a medication used to treat moderate to severe Alzheimer's disease. This medication needs to be avoided in clients with severe renal dysfunction, and a reduced dosage is needed in moderate renal dysfunction. The other options are not specifically associated with this medication.
A client has been defibrillated at 360 joules (monophasic) and the attempts to convert the ventricular fibrillation (VF) were unsuccessful. Based on an evaluation of the situation, the nurse determines that which action is best?
- A. Terminating the resuscitation effort
- B. Preparing for the administration of sodium bicarbonate intravenously
- C. Performing cardiopulmonary resuscitation (CPR) for 5 cycles or about 2 minutes
- D. Performing CPR for 5 minutes, then defibrillating 3 more times at 400 joules
Correct Answer: C
Rationale: Defibrillation is an asynchronous countershock used to terminate pulseless ventricular tachycardia (VT) or ventricular fibrillation (VF). The defibrillator is charged to 120 to 200 joules (biphasic) or 300 joules (monophasic) for 1 countershock from the defibrillator, and then CPR is immediately resumed and continued for 5 cycles or about 2 minutes. The rhythm is reassessed after 2 minutes and if VF or pulseless VT continues, the defibrillator is charged to give a second shock at the same energy level previously used. CPR is resumed after the shock if needed and the life support protocol is continued. There is no information in the question to indicate that life support should be terminated. Sodium bicarbonate may be prescribed but is not the best action. Giving CPR for 5 minutes may not help oxygenation to the brain and myocardium and is not the best action.
Which of the following is not considered one of the 'Ten Rights of Medication Administration'?
- A. The 'right' verification
- B. The 'right' to refuse
- C. The 'right' documentation
- D. The 'right' client education
Correct Answer: A
Rationale: The Ten Rights of Medication Administration include right patient, drug, dose, route, time, documentation, reason, response, refusal, and education. 'Right verification' is not a standard right.
You are caring for a group of elderly clients, many of whom are affected with multiple chronic disorders and are also, at times, affected with some acute disorders that require medical and nursing attention. As you are caring for these clients some will need a new medication regimen for an acute disorder. You should consider that fact that the elderly population is at risk for more side effects, adverse drug reactions, and toxicity and over dosages of medications because the elderly have a (n):
- A. Increased creatinine clearance.
- B. Impaired immune system.
- C. Decreased hepatic metabolism.
- D. Increased bodily fat.
Correct Answer: C
Rationale: Elderly individuals often have decreased hepatic metabolism due to reduced liver function, which affects drug metabolism and increases the risk of side effects, adverse reactions, and toxicity.
The nurse is preparing to perform a Mantoux tuberculin skin test. Which interventions apply to the administration of this test? Select all that apply.
- A. Explain the procedure to the client.
- B. Obtain a 3-mL syringe with a 1/2-inch needle for the injection.
- C. Mark the test area to locate it for reading 48 to 72 hours after injection.
- D. Bunch up the skin and insert the needle with the needle bevel facing downward.
- E. Cleanse the injection site on the lower dorsal surface of the forearm with alcohol and allow it to dry.
- F. Ask the client about a history of receiving a positive purified protein derivative (PPD) reaction.
Correct Answer: A,C,E,F
Rationale: The nurse should always explain the procedure to the client and then assess him or her for a history of a PPD reaction. The test should not be administered if the client has such a history. The nurse should use a tuberculin syringe (not a 3-mL syringe) with a 1/2-inch 26- or 27-gauge needle. The injection site on the lower dorsal surface of the forearm is cleansed with alcohol and allowed to dry. The skin is stretched taut, and 0.1 mL of solution containing 0.5 tuberculin units of PPD is injected. The injection is made just under the surface of the skin with the needle bevel facing upward to provide a discrete elevation of the skin (a wheal) 6 to 10 mm in diameter. The test area is marked to locate it for reading and the test area is read 48 to 72 hours after injection.
