What instruction should be provided to a client with a history of myocardial infarction (MI) who is prescribed nitroglycerin?
- A. Take nitroglycerin with food to avoid stomach upset.
- B. Store nitroglycerin tablets in a dark, glass container.
- C. Swallow nitroglycerin tablets whole without chewing.
- D. Discontinue the medication if a headache occurs.
Correct Answer: B
Rationale: The correct answer is B because nitroglycerin tablets should be stored in a dark, glass container to protect them from light and moisture, which could decrease their effectiveness. Storing them in any other container could lead to degradation of the medication.
Choice A is incorrect because nitroglycerin should be taken sublingually, not with food. Choice C is incorrect because nitroglycerin should be placed under the tongue to be absorbed quickly, not swallowed whole. Choice D is incorrect because experiencing a headache is a common side effect of nitroglycerin and does not indicate that the medication should be discontinued.

In evaluating a 10-year-old child with meningitis suspected of having diabetes insipidus, which finding is indicative of diabetes insipidus?
- A. Decreased urine specific gravity.
- B. Elevated urine glucose.
- C. Decreased serum potassium.
- D. Increased serum sodium.
Correct Answer: A
Rationale: The correct answer is A: Decreased urine specific gravity. In diabetes insipidus, there is an inability to concentrate urine, leading to decreased urine specific gravity. This is due to the decreased production or action of antidiuretic hormone (ADH). As a result, the kidneys are unable to reabsorb water efficiently, causing dilute urine with low specific gravity.
Incorrect choices:
B: Elevated urine glucose is more indicative of diabetes mellitus, not diabetes insipidus.
C: Decreased serum potassium is not a typical finding in diabetes insipidus.
D: Increased serum sodium can occur due to dehydration from excessive urination in diabetes insipidus, but it is not directly indicative of the condition.
When assessing a client reporting severe pain in the right lower quadrant of the abdomen, which sign would most likely indicate appendicitis?
- A. Rebound tenderness at McBurney's point.
- B. Positive Murphy's sign.
- C. Rovsing's sign.
- D. Cullen's sign.
Correct Answer: A
Rationale: The correct answer is A: Rebound tenderness at McBurney's point. McBurney's point is located in the right lower quadrant and is a classic sign of appendicitis. Rebound tenderness at this point indicates inflammation in the peritoneum, suggesting appendicitis. Choices B, C, and D are not specific to appendicitis. Positive Murphy's sign is related to cholecystitis, Rovsing's sign is seen in acute appendicitis but is not as specific as rebound tenderness at McBurney's point, and Cullen's sign is associated with acute pancreatitis.
A client with a history of diabetes mellitus is admitted with a foot ulcer. The nurse should recognize that which intervention is most critical in promoting healing of the foot ulcer?
- A. Strict control of blood glucose levels.
- B. Regular dressing changes with sterile technique.
- C. Application of antibiotic ointment.
- D. Hydrotherapy treatment daily.
Correct Answer: A
Rationale: Correct Answer: A
Rationale:
1. Strict control of blood glucose levels is critical in promoting healing of foot ulcers in diabetic patients.
2. High blood glucose levels can impair wound healing by affecting circulation and immune response.
3. Maintaining normal glucose levels helps optimize tissue repair and prevent further complications.
4. Regular dressing changes (B) are important but not as critical as controlling blood glucose levels.
5. Application of antibiotic ointment (C) may be necessary for infected ulcers, but not the most critical intervention.
6. Hydrotherapy treatment (D) can help with wound cleansing, but it is not as essential as controlling blood glucose levels.
A 38-year-old male client collapsed at his outside construction job in Texas in July. His admitting vital signs to ICU are, BP 82/70, heart rate 140 beats/minute, urine output 10 ml/hr, skin cool to the touch. Pulmonary artery (PA) pressures are, PAWP 1, PAP 8/2, RAP -1, SVR 1600. What nursing action has the highest priority?
- A. Apply a hypothermia unit to stabilize core temperature.
- B. Increase the client's IV fluid rate to 200 ml/hr.
- C. Call the hospital chaplain to counsel the family.
- D. Draw blood cultures x3 to detect infection.
Correct Answer: B
Rationale: The correct answer is B: Increase the client's IV fluid rate to 200 ml/hr. The client's vital signs indicate hypotension, tachycardia, decreased urine output, and cool skin, suggesting hypovolemic shock. Increasing IV fluid rate will help to restore intravascular volume and improve perfusion to vital organs. This is the highest priority as it addresses the immediate physiological need for circulatory support.
Choice A is incorrect because hypothermia is not indicated based on the client's presentation. Choice C is incorrect as it does not address the client's urgent physiological needs. Choice D is incorrect as drawing blood cultures, while important, is not the most immediate priority in this situation.
Which assessment finding indicates a client's readiness to leave the nursing unit for a bronchoscopy?
- A. Client denies allergies to contrast media.
- B. Skin prep to insertion site completed.
- C. On-call sedation administered.
- D. Oxygen at 2 L/minute via nasal cannula.
Correct Answer: C
Rationale: Rationale: Option C, on-call sedation administered, is the correct answer because sedation is essential for bronchoscopy to ensure the client is comfortable and cooperative during the procedure. Sedation helps reduce anxiety and discomfort, making the procedure more tolerable. Options A, B, and D are incorrect as they do not directly indicate readiness for the procedure. Denying allergies to contrast media (A) is important but not specific to bronchoscopy readiness. Skin prep completion (B) is part of the pre-procedure preparation but does not confirm readiness. Oxygen administration (D) is a routine care measure and does not indicate readiness for bronchoscopy.
