Nursing Elites

1. A nurse is obtaining the medical history of a client who has a new prescription for isosorbide mononitrate. Which of the following should the nurse identify as a contraindication to this medication?

• A. Glaucoma
• B. Hypertension
• C. Polycythemia
• D. Migraine headaches

Correct answer: A

Rationale: Isosorbide mononitrate is contraindicated in clients with glaucoma due to its potential to increase intraocular pressure, which can exacerbate the condition. Hypertension, polycythemia, and migraine headaches are not contraindications for isosorbide mononitrate. In fact, isosorbide mononitrate is commonly used in the management of hypertension and certain types of angina.

2. A healthcare professional is reviewing the results of an ABG performed on a client with chronic emphysema. Which of the following results suggests the need for further treatment?

• A. PaO2 level of 89 mm Hg
• B. PaCO2 level of 55 mm Hg
• C. HCO3 level of 25 mEq/L
• D. pH level of 7.37

Correct answer: B

Rationale: A PaCO2 level of 55 mm Hg indicates hypercapnia, which is common in clients with emphysema but may require further treatment if it leads to respiratory acidosis or distress. Elevated PaCO2 levels can indicate inadequate ventilation and impaired gas exchange, potentially leading to respiratory acidosis. The other results fall within normal ranges or compensated values for a client with chronic emphysema and do not necessarily indicate the need for immediate intervention.

3. A nurse is assessing a newborn whose mother had gestational diabetes. Which of the following findings should the nurse identify as a manifestation of hypoglycemia?

• A. Hypertonia
• B. Jitteriness
• C. Acrocyanosis
• D. Generalized petechiae

Correct answer: B

Rationale: Jitteriness is a common sign of hypoglycemia in newborns. Other signs may include irritability, poor feeding, and lethargy. Choice A, Hypertonia, is not typically associated with hypoglycemia but rather with conditions like hypocalcemia. Acrocyanosis (Choice C) is a benign condition characterized by peripheral cyanosis and is not directly linked to hypoglycemia. Generalized petechiae (Choice D) are tiny red or purple spots on the skin due to bleeding and are not specific to hypoglycemia.

4. A nurse is reviewing laboratory results for a client who has chronic kidney disease. Which of the following findings should the nurse expect?

• A. Hypernatremia
• B. Hypocalcemia
• C. Low potassium
• D. Low magnesium

Correct answer: B

Rationale: In chronic kidney disease, the kidneys have impaired ability to activate vitamin D, leading to decreased production of calcitriol. Calcitriol is essential for calcium absorption in the intestines. Therefore, hypocalcemia is a common finding in chronic kidney disease. Hypernatremia (increased sodium levels) is not typically associated with chronic kidney disease. Low potassium and low magnesium are possible electrolyte imbalances in chronic kidney disease, but they are not as directly related to the impaired activation of vitamin D as hypocalcemia.

5. A client with a closed head injury has their eyes open when pressure is applied to the nail beds, and they exhibit adduction of the arms with flexion of the elbows and wrists. The client also moans with stimulation. What is the client's Glasgow Coma Score?

• A. 4
• B. 7 (comatose)
• C. 9
• D. 10

Correct answer: B

Rationale: The client's Glasgow Coma Score is 7. This is calculated by assigning 2 points for eye-opening to pain, 2 points for incomprehensible sounds, and 3 points for flexion posturing. Choices A, C, and D are incorrect. Choice A (4) would be the score if the client displayed decerebrate posturing instead of flexion posturing. Choice C (9) would be the score if the client exhibited eye-opening to speech, confused speech, and decorticate posturing. Choice D (10) would be the score if the client showed eye-opening spontaneously, oriented speech, and obeyed commands, which is not the case here.
