Question 1 of 5
A client attached to mechanical ventilation suddenly becomes restless and pulls out the tracheostomy tube. Which is the nurse's priority intervention?
Correct Answer: D
Rationale: If a tracheostomy tube is dislodged, checking for spontaneous breathing (D) is the priority to assess airway patency and oxygenation need. Preparing for reintubation (A) or calling teams (B, C) follows. D is correct. Rationale: Assessing breathing determines if immediate reinsertion or oxygenation is urgent, guiding next steps per respiratory emergency standards, ensuring patient stability first.
Question 2 of 5
A client is scheduled for a computed tomography (CT) of the brain with contrast. When reviewing the client's medical record, what significant finding should the nurse report to the primary healthcare provider before the diagnostic procedure?
Correct Answer: A
Rationale: Metformin (A) is significant before a CT with contrast due to lactic acidosis risk if renal function declines from contrast dye. NPO status (B) isn't critical for brain CT. Gadolinium (C) is MRI-related, not CT. Bowel prep (D) is irrelevant. A is correct. Rationale: Contrast can impair kidneys, exacerbating metformin toxicity, requiring provider adjustment, per radiology safety protocols.
Question 3 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 4 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 5 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.
