Nursing Elites

1. A client has the following arterial blood gas (ABG) results: pH 7.51, PCO2 31 mm Hg, PO2 94 mm Hg, HCO3 24 mEq/L. Which of the following acid-base disturbances does the nurse recognize in these results?

• A. Metabolic acidosis
• B. Metabolic alkalosis
• C. Respiratory acidosis
• D. Respiratory alkalosis

Correct answer: D

Rationale: The ABG results show a pH above the normal range (7.35-7.45) and a decreased PCO2, indicating respiratory alkalosis. In respiratory alkalosis, the pH is increased and the PCO2 is decreased. Metabolic acidosis (choice A) would present with a low pH and low HCO3 levels. Metabolic alkalosis (choice B) would show an increased pH and HCO3 levels. Respiratory acidosis (choice C) would have a low pH and an increased PCO2.

2. When preparing a client for intravenous pyelography (IVP), which action by the nurse is most important?

• A. Administering a sedative
• B. Encouraging fluid intake
• C. Administering an oral preparation of radiopaque dye
• D. Questioning the client about allergies to iodine or shellfish

Correct answer: D

Rationale: The most crucial action for the nurse when preparing a client for intravenous pyelography (IVP) is to question the client about allergies to iodine or shellfish. Some IVP dyes contain iodine, and if the client is allergic to iodine or shellfish, they may experience severe allergic reactions such as itching, hives, rash, throat tightness, difficulty breathing, or bronchospasm. Administering a sedative (Choice A) may be needed for relaxation during the procedure, encouraging fluid intake (Choice B) is generally beneficial but not the most crucial for IVP preparation, and administering radiopaque dye (Choice C) should only be done after confirming the client's safety regarding allergies to iodine or shellfish.

3. In a patient with diabetes mellitus, which of the following is a sign of hypoglycemia?

• A. Polydipsia.
• B. Polyuria.
• C. Sweating.
• D. Dry skin.

Correct answer: C

Rationale: Sweating is a common sign of hypoglycemia in diabetic patients. When blood sugar levels drop too low, the body releases stress hormones like adrenaline, which can cause sweating as a response to the perceived danger. Polydipsia (excessive thirst) and polyuria (excessive urination) are actually more commonly associated with hyperglycemia, not hypoglycemia. Dry skin is not typically a sign of hypoglycemia.

4. The nurse is preparing to administer amoxicillin (Amoxil) to a patient and learns that the patient previously experienced a rash when taking penicillin. Which action will the nurse take?

• A. Administer the amoxicillin and have epinephrine available.
• B. Ask the provider to order an antihistamine.
• C. Contact the provider to discuss using a different antibiotic.
• D. Request an order for a beta-lactamase-resistant drug.

Correct answer: C

Rationale: When a patient has a history of rash from penicillin, it indicates a potential allergic reaction to penicillin and other related drugs, such as amoxicillin. It is crucial to avoid administering penicillins to such patients unless there is no alternative. The nurse's best action in this situation is to contact the provider to discuss using a different antibiotic from a different class. This approach helps prevent potential severe allergic reactions. While epinephrine and antihistamines are used to manage allergic reactions, administering amoxicillin despite the known allergy is not advisable and could lead to serious consequences. Requesting a beta-lactamase-resistant drug does not address the issue of potential allergic reactions in this scenario.

5. Which of the following is a key symptom of hypothyroidism?

• A. Weight loss.
• B. Heat intolerance.
• C. Cold intolerance.
• D. Increased appetite.

Correct answer: C

Rationale: Cold intolerance is a key symptom of hypothyroidism because a decreased metabolic rate leads to a reduced ability to regulate body temperature. Weight loss (Choice A) is more commonly associated with hyperthyroidism, where the metabolic rate is increased. Heat intolerance (Choice B) is also more indicative of hyperthyroidism, where excess thyroid hormone leads to an increased sensitivity to heat. Increased appetite (Choice D) is not typically seen in hypothyroidism; instead, individuals with hypothyroidism may experience weight gain due to the slowed metabolism.
