Nursing Elites

1. A client is brought to the emergency department by a neighbor. The client is lethargic and has a fruity odor on the breath. The client’s arterial blood gas (ABG) results are pH 7.25, PCO2 34 mm Hg, PO2 86 mm Hg, HCO3 14 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: A

Rationale: The correct answer is 'Metabolic acidosis.' Metabolic acidosis is characterized by a low pH (<7.35) and a low bicarbonate level (HCO3 <22 mEq/L). In this case, the client's ABG results show a pH of 7.25 and an HCO3 level of 14 mEq/L, indicating metabolic acidosis. The PCO2 of 34 mm Hg is normal, ruling out respiratory acidosis or alkalosis. The PO2 of 86 mm Hg is also within the normal range and is not indicative of a respiratory problem. Therefore, the client is experiencing metabolic acidosis based on the ABG results provided.

2. Assessment of the diabetic client for common complications should include examination of the:

• A. Abdomen.
• B. Lymph glands.
• C. Pharynx.
• D. Eyes.

Correct answer: D

Rationale: The correct answer is D: Eyes. Diabetic clients are at high risk of developing complications such as diabetic retinopathy, making regular eye examinations crucial. Assessing the eyes helps in early detection and management of diabetic eye diseases. Choices A, B, and C are incorrect because while they may be relevant in certain assessments, they are not commonly associated with complications specific to diabetes. Examination of the abdomen, lymph glands, and pharynx are not typically part of routine assessments for common complications in diabetic clients.

3. The client with type 1 diabetes mellitus is taught to take isophane insulin suspension NPH (Humulin N) at 5 PM each day. The client should be instructed that the greatest risk of hypoglycemia will occur at about what time?

• A. 11 AM, shortly before lunch.
• B. 1 PM, shortly after lunch.
• C. 6 PM, shortly after dinner.
• D. 1 AM, while sleeping.

Correct answer: D

Rationale: The correct answer is D, 1 AM, while sleeping. Isophane insulin suspension NPH (Humulin N) peaks around 6-8 hours after administration, which increases the risk of hypoglycemia during the night. Choice A, 11 AM, shortly before lunch, is incorrect because the peak effect of NPH insulin occurs much later. Choice B, 1 PM, shortly after lunch, is incorrect as it is too early for the peak effect of NPH insulin. Choice C, 6 PM, shortly after dinner, is also incorrect because the peak risk of hypoglycemia with NPH insulin occurs later in the night.

4. A client is to have a transsphenoidal hypophysectomy to remove a large, invasive pituitary tumor. The nurse should instruct the client that the surgery will be performed through an incision in the:

• A. Back of the mouth.
• B. Nose.
• C. Sinus channel below the right eye.
• D. Upper gingival mucosa in the space between the upper gums and lip.

Correct answer: D

Rationale: The correct answer is D: Upper gingival mucosa in the space between the upper gums and lip. A transsphenoidal hypophysectomy involves accessing the pituitary gland through an incision in the upper gingival mucosa, providing direct access to the pituitary gland without external scars. Choices A, B, and C are incorrect because the surgery is not performed through the back of the mouth, the nose, or the sinus channel below the right eye. It is crucial for the client to understand the specific location of the incision to ensure accurate preoperative education and expectations.

5. The nurse is caring for a patient who is receiving an intravenous antibiotic. The nurse notes that the provider has ordered serum drug peak and trough levels. The nurse understands that these tests are necessary for which type of drugs?

• A. Drugs with a broad spectrum
• B. Drugs with a narrow spectrum
• C. Drugs with a broad therapeutic index
• D. Drugs with a narrow therapeutic index

Correct answer: D

Rationale: Medications with a narrow therapeutic index have a limited range between the therapeutic dose and a toxic dose. It is important to monitor these medications closely by evaluating regular serum peak and trough levels. Drugs with a narrow spectrum (Choice B) are antibiotics that target only a limited group of bacteria, not related to the need for peak and trough monitoring. Drugs with a broad spectrum (Choice A) cover a wide range of bacteria, but this characteristic does not determine the need for peak and trough monitoring. Drugs with a broad therapeutic index (Choice C) have a wide safety margin between therapeutic and toxic doses, so they typically do not require peak and trough level monitoring.
