Nursing Elites

1. Your patient has shown the following signs and symptoms: Feeling very thirsty, large amount of water intake, dryness of the mouth, and urinary frequency. What physical disorder does this patient most likely have?

• A. Diabetes
• B. Angina
• C. Hypertension
• D. Hypotension

Correct answer: A

Rationale: The patient is exhibiting classic signs of diabetes, such as polydipsia (feeling very thirsty), polyuria (large amount of water intake and urinary frequency), and xerostomia (dryness of the mouth). These symptoms are indicative of high blood glucose levels, which are characteristic of diabetes. Other common signs of diabetes include poor vision, unexplained weight loss, peripheral neuropathy (tingling in the feet and hands), and fatigue. Angina is chest pain due to reduced blood flow to the heart, not associated with the symptoms described in the patient. Hypertension is high blood pressure, which typically does not present with these specific symptoms related to diabetes. Hypotension is low blood pressure and is not consistent with the signs and symptoms presented by the patient, pointing more towards diabetes as the likely diagnosis.

2. Based on the information given, which patient would be an appropriate candidate for a closed MRI without contrast?

• A. A 20-year-old woman with unexplained joint pain and a low BMI.
• B. A 35-year-old woman with Multiple Sclerosis who is trying to conceive.
• C. A 67-year-old man who had open-heart surgery 4 years ago.
• D. A 40-year-old woman in a hypomanic state for the last 2 days.

Correct answer: A

Rationale: The correct answer is the 20-year-old woman with unexplained joint pain and a low BMI. MRI can be used to diagnose musculoskeletal disorders, and this patient has no contraindications to an MRI. Choice B is incorrect because using MRI without contrast may not be ideal for a patient trying to conceive. Choice C is incorrect as the patient's past open-heart surgery may pose risks for an MRI without contrast. Choice D is incorrect since the patient's hypomanic state does not indicate a need for an MRI without contrast for joint pain.

3. A client in the ICU has been intubated and placed on a ventilator. The physician orders synchronous intermittent mandatory ventilation (SIMV). Which statement best describes the work of this mode of ventilation?

• A. The ventilator delivers a set rate and tidal volume regardless of whether the client is attempting to breathe
• B. The ventilator coordinates delivered breaths with the client's respiratory efforts
• C. The ventilator provides a supplemental breath for every third breath of the client
• D. The ventilator provides breaths during the expiratory phase of the client's respirations

Correct answer: B

Rationale: Synchronous intermittent mandatory ventilation (SIMV) is a ventilation mode that coordinates delivered breaths with the client's own respiratory efforts. This mode allows the client to initiate breaths, with the ventilator providing preset breaths at a controlled rate and volume. Option A is incorrect because in SIMV, the ventilator syncs with the client's respiratory efforts. Option C is incorrect as it does not accurately depict the way SIMV works. Option D is also incorrect as SIMV does not specifically provide breaths during the expiratory phase of the client's respirations. Therefore, the correct answer is B, where the ventilator coordinates breath delivery with the client's breathing efforts.

4. A patient with a history of diabetes mellitus is on the second postoperative day following cholecystectomy. She has complained of nausea and isn't able to eat solid foods. The nurse enters the room to find the patient confused and shaky. Which of the following is the most likely explanation for the patient's symptoms?

• A. Anesthesia reaction
• B. Hyperglycemia
• C. Hypoglycemia
• D. Diabetic ketoacidosis

Correct answer: C

Rationale: In a postoperative diabetic patient who is unable to eat solid foods, the likely cause of symptoms such as confusion and shakiness is hypoglycemia. Confusion and shakiness are common manifestations of hypoglycemia. Insufficient glucose supply to the brain (neuroglycopenia) can lead to confusion, difficulty with concentration, irritability, hallucinations, focal impairments like hemiplegia, and, in severe cases, coma and death. Anesthesia reaction (Choice A) is less likely in this scenario as the patient is already on the second postoperative day. Hyperglycemia (Choice B) is unlikely given the patient's symptoms and history of not eating. Diabetic ketoacidosis (Choice D) typically presents with hyperglycemia, ketosis, and metabolic acidosis, which are not consistent with the patient's current symptoms of confusion and shakiness.

5. Which pathologic condition is described as 'increased intraocular pressure of the eye'?

• A. Detached Retina
• B. Fovea Centralis
• C. Presbyopia
• D. Glaucoma

Correct answer: D

Rationale: The correct answer is Glaucoma. Glaucoma is a condition characterized by increased intraocular pressure in the eye, which can lead to optic nerve damage, vision loss, and blindness if left untreated. Detached Retina (A), Fovea Centralis (B), and Presbyopia (C) are not conditions associated with increased intraocular pressure like Glaucoma. Detached Retina is a separation of the retina from its underlying tissue, Fovea Centralis is a part of the retina responsible for sharp central vision, and Presbyopia is an age-related condition affecting near vision due to the loss of flexibility in the eye's lens.
