Question 1 of 5
The nurse is reviewing the arterial blood gas results of an assigned client. Which arterial blood gases indicate metabolic alkalosis?
Correct Answer: D
Rationale: Metabolic alkalosis features high pH (>7.45) and elevated HCO3- (>26 mEq/L) with normal Pco2 (35-45 mm Hg). Option D (pH 7.48, Pco2 40, HCO3- 36) fits this, indicating excess base. A is respiratory acidosis. B is normal. C is compensated. D is correct. Rationale: High HCO3- from vomiting or diuretics causes alkalosis, uncompensated here, per ABG interpretation principles.
Question 2 of 5
After a head injury, a client develops a deficiency of antidiuretic hormone (ADH). What should the nurse consider before assessing the patient about the response to secretion of ADH?
Correct Answer: B
Rationale: ADH deficiency (diabetes insipidus) post-head injury causes dilute urine (B) due to reduced water reabsorption. Osmolality increases (A) is a result, not a cause. GFR (C) isn't primarily affected. Reabsorption (D) decreases. B is correct. Rationale: Low ADH leads to polyuria with low urine concentration, a key assessment in DI, per endocrine trauma care.
Question 3 of 5
The laboratory reports of a client who underwent a hypophysectomy show an intracranial pressure (ICP) of $20 \mathrm{mmHg}$. Which action made by the client is responsible for this condition?
Correct Answer: C
Rationale: ICP of 20 mmHg (elevated) post-hypophysectomy is likely from bending over (C), increasing venous pressure to the brain. Drinking (A) or eating fiber (B) don't directly raise ICP. Knee bending (D) is safe. C is correct. Rationale: Bending elevates intracranial venous return, spiking ICP in a fragile post-surgical state, per neurocare principles, unlike neutral activities.
Question 4 of 5
During a physical assessment, a client was diagnosed with increased temperature due to an increased basal metabolic rate (BMR). Which hormonal imbalances may the client have? Select all that apply.
Correct Answer: B
Rationale: Increased BMR with elevated temperature suggests thyroid (B) excess (hyperthyroidism), boosting metabolism. Cortisol (A) affects stress, not BMR primarily. Estrogen (C) and testosterone (D) influence other systems. B is correct. Rationale: Thyroid hormones (T3, T4) directly raise BMR and heat, a classic endocrine imbalance, per physiology, unlike other hormones with indirect effects.
Question 5 of 5
The nurse is caring for a client with a T4 spinal cord injury. Which finding indicates that the client is experiencing neurogenic shock?
Correct Answer: A
Rationale: Neurogenic shock in T4 SCI features hypotension and bradycardia (A, 82/40, 48 bpm) from sympathetic loss. Hypertension/tachycardia (B) suggests dysreflexia. C and D are normalish. A is correct. Rationale: Loss of vasomotor tone below T4 causes vasodilation and unopposed vagal activity, per SCI pathophysiology, requiring fluids and atropine.
