Extract:
Question 1 of 5
Laboratory tests reveal the following electrolyte values for Mr. Smith: Na 135 mEq/L, Ca 8.5 mg/dL, Cl 102 mEq/L, and K 2.0 mEq/L. Which of the following values should the nurse report to the physician because of its potential risk to the client?
Correct Answer: B
Rationale: The correct answer is 'K.' Normal serum potassium levels range between 3.5 and 5.5 mEq/L. Mr. Smith's potassium level of 2.0 mEq/L is significantly below the normal range, indicating hypokalemia, which can lead to serious risks such as cardiac arrhythmias. The levels of sodium (Na), calcium (Ca), and chloride (Cl) are within normal ranges, so they do not pose an immediate risk to the client's health.
Therefore, the nurse should report the low potassium level to the physician for prompt intervention.
Question 2 of 5
During a home health visit, a nurse consults with a male patient diagnosed with CAD and COPD who is taking Ventolin, Azmacort, Aspirin, and Theophylline and complains of upset stomach, nausea, and discomfort. What should the nurse do?
Correct Answer: A
Rationale: The correct answer is to contact the patient's physician immediately. The patient's symptoms of upset stomach, nausea, and discomfort could indicate theophylline toxicity, a potentially serious condition. It is crucial to consult the physician promptly to address this issue. Option B, recommending the patient lie on his right side, is incorrect as it does not address the potential theophylline toxicity and is not a priority. Option C, advising the patient to schedule a doctor's visit the next day, is inappropriate as the symptoms may indicate an urgent concern. Option D, suggesting holding the drug Azmacort, is incorrect as it does not address the potential theophylline toxicity and should not be done without consulting the physician first.
Question 3 of 5
Which physiologic mechanism best describes the function of the sodium-potassium pump?
Correct Answer: A
Rationale: Active transport is the correct answer as it accurately describes the process involved in the sodium-potassium pump. The pump utilizes energy to move ions against their concentration gradient, maintaining cellular concentrations. Diffusion (choice
B) is a passive process where substances move from an area of higher concentration to lower concentration. Filtration (choice
C) involves the movement of solutes based on pressure gradients. Osmosis (choice
D) is the movement of water across a semipermeable membrane.
Question 4 of 5
A patient's nurse taking a history notes complaints of SOB and weakness in the lower extremities. The patient has a history of hyperlipidemia and hypertension. Which of the following may be occurring?
Correct Answer: B
Rationale: In this scenario, the patient's symptoms of shortness of breath (SO
B) and weakness in the lower extremities, along with a history of hyperlipidemia and hypertension, are suggestive of a myocardial infarction (MI). It is important to note that MI can present with a variety of symptoms, including those affecting the respiratory system and muscle weakness.
Choices A, C, and D are incorrect because the patient's symptoms are more indicative of a myocardial infarction rather than congestive heart failure (CHF), chronic obstructive pulmonary disease (COP
D), or peripheral vascular disease (PV
D).
Question 5 of 5
A client with sickle cell disease is worried about passing the disease on to children. Which of the following statements by the PN is most appropriate for this client?
Correct Answer: B
Rationale: A client with sickle cell disease has a genetic condition that can be passed on to their offspring. The most appropriate statement for the PN to provide is to acknowledge this fact and inform the client that sickle cell disease is genetically based and might be passed on to children. This empowers the client with accurate information.
Choice A has been refined to emphasize discussing the inheritance risk, making it a better option than the vague original choice.
Choices C and D provide incorrect information. Sickle cell disease is indeed genetically based and can be inherited.
