Nursing Elites

1. A client with diabetes mellitus is experiencing polyuria, polydipsia, and polyphagia. What do these symptoms indicate?

• A. Hypoglycemia
• B. Diabetic ketoacidosis (DKA)
• C. Hyperosmolar hyperglycemic state (HHS)
• D. Insulin shock

Correct answer: B

Rationale: Polyuria, polydipsia, and polyphagia are classic signs of diabetic ketoacidosis (DKA), which occurs due to a combination of hyperglycemia and ketone production. Hypoglycemia (Choice A) is characterized by low blood sugar levels, leading to symptoms like confusion, shakiness, and sweating, which are different from the symptoms described in the scenario. Hyperosmolar hyperglycemic state (HHS) (Choice C) typically presents with severe hyperglycemia, dehydration, and altered mental status, rather than the triad of symptoms mentioned. Insulin shock (Choice D) refers to a severe hypoglycemic reaction due to excessive insulin, manifesting with confusion, sweating, and rapid heartbeat, not the symptoms seen in the client with diabetes mellitus described in this scenario.

2. A client who is experiencing respiratory distress is admitted with respiratory acidosis. Which pathophysiological process supports the client’s respiratory acidosis?

• A. Low oxygen levels are present in the blood.
• B. High levels of carbon dioxide have accumulated in the blood.
• C. Increased bicarbonate levels are causing alkalosis.
• D. Respiratory rate is increased, causing hyperventilation.

Correct answer: B

Rationale: High levels of carbon dioxide in the blood lead to respiratory acidosis due to inadequate ventilation. The correct answer is B. In respiratory acidosis, the accumulation of carbon dioxide in the blood occurs due to inadequate exhalation, leading to acidosis. Choice A is incorrect as low oxygen levels are related to hypoxemia, not respiratory acidosis. Choice C is incorrect as increased bicarbonate levels would lead to alkalosis, not acidosis. Choice D is incorrect as an increased respiratory rate causing hyperventilation would actually help decrease carbon dioxide levels, not lead to respiratory acidosis.

3. When planning care for a client newly diagnosed with open-angle glaucoma, the nurse identifies a priority nursing problem of visual sensory/perceptual alterations. This problem is based on which etiology?

• A. Limited eye movement.
• B. Decreased peripheral vision.
• C. Blurred distance vision.
• D. Photosensitivity.

Correct answer: B

Rationale: The correct answer is B: Decreased peripheral vision. In open-angle glaucoma, decreased peripheral vision is a characteristic symptom resulting from increased intraocular pressure. This visual impairment can lead to sensory/perceptual alterations. Choice A, limited eye movement, is not directly associated with the pathophysiology of open-angle glaucoma. Choice C, blurred distance vision, is more commonly seen in conditions like myopia or presbyopia. Choice D, photosensitivity, is not a typical manifestation of open-angle glaucoma and is more commonly associated with conditions like migraines or certain medications.

4. After a CT scan with intravenous contrast medium, a client returns to the room complaining of shortness of breath and itching. Which intervention should the nurse implement?

• A. Call respiratory therapy to administer a breathing treatment.
• B. Send for an emergency tracheostomy set.
• C. Prepare a dose of epinephrine.
• D. Review the client's complete list of allergies.

Correct answer: C

Rationale: Preparing a dose of epinephrine is the correct intervention in this situation as the client is displaying symptoms of an anaphylactic reaction to the contrast medium used during the CT scan. Epinephrine is the first-line treatment for anaphylaxis due to its ability to reverse the symptoms rapidly. Calling respiratory therapy for a breathing treatment (Choice A) may not address the underlying allergic reaction and delay appropriate treatment. Sending for an emergency tracheostomy set (Choice B) is not indicated as the client's symptoms suggest an allergic reaction rather than airway obstruction. Reviewing the client's complete list of allergies (Choice D) is important but would not provide immediate relief for the client's current symptoms; administering epinephrine takes precedence in this situation.

5. A client with asthma is prescribed a metered-dose inhaler (MDI) with albuterol. Which instruction is essential for the nurse to provide?

• A. Use the inhaler only before bedtime
• B. Shake the inhaler well before use
• C. Exhale fully before inhaling the medication
• D. Take two puffs every hour

Correct answer: B

Rationale: The correct answer is to 'Shake the inhaler well before use.' This instruction is crucial as shaking the inhaler ensures the proper mixing of the medication, which is essential for its effective delivery. Option A is incorrect because using the inhaler only before bedtime may not provide adequate relief during the day. Option C is incorrect as exhaling fully is a good practice but not the most essential instruction. Option D is incorrect as taking two puffs every hour may exceed the recommended dosage and lead to adverse effects.
