When a blood pressure cuff is too wide for a client's arm, what type of reading might this blood pressure cuff produce?
- A. A normal reading
- B. An abnormally low reading
- C. An abnormally high reading
- D. A fluctuating reading
Correct Answer: B
Rationale: When a blood pressure cuff is too wide for a client's arm, it may produce an abnormally low blood pressure reading. This occurs because the oversized cuff can lead to an underestimation of blood pressure. It is essential to ensure that the cuff fits appropriately to obtain an accurate reading. An abnormally high reading (Choice C) is less likely with an oversized cuff, as it generally leads to lower readings. A normal reading (Choice A) is unlikely due to the inaccuracies caused by the oversized cuff. A fluctuating reading (Choice D) is not a typical result of using a cuff that is too wide; instead, it usually leads to consistently low readings.

Which of the following statements best describes compartment syndrome?
- A. An injury causes pain and tingling that starts in the buttock and travels down the leg.
- B. An injury causes swelling within muscle tissue that leads to anoxia of nerves and muscles.
- C. An injury causes permanent flexion of the interphalangeal joint, resulting in deformity.
- D. An injury causes pain and swelling of the median plantar nerve.
Correct Answer: B
Rationale: Compartment syndrome is characterized by swelling and increased pressure within a muscle compartment, leading to decreased blood flow and oxygen supply to nerves and muscles. This can result from various causes, such as trauma or the application of a cast after a fracture. If left untreated, compartment syndrome can lead to tissue necrosis. Choice A is incorrect as pain and tingling starting in the buttock and traveling down the leg are not specific features of compartment syndrome. Choice C is incorrect as permanent flexion of the interphalangeal joint is unrelated to compartment syndrome. Choice D is incorrect as pain and swelling of the median plantar nerve do not describe compartment syndrome.
A nurse is caring for an 83-year-old man who has had swallowing difficulties. All of the following interventions are appropriate for this client EXCEPT:
- A. Keep the client in an upright position at all times
- B. Auscultate lung sounds every shift and after feedings
- C. Maintain suction equipment at the client's bedside
- D. Instruct the client about how to perform swallowing exercises
Correct Answer: A
Rationale: When caring for a client with swallowing difficulties, it is crucial to prevent aspiration of food into the lungs. Appropriate interventions include auscultating lung sounds every shift and after feedings to assess for any changes in breathing patterns, maintaining suction equipment at the client's bedside in case of difficulties, and providing instruction on swallowing exercises. Keeping the client in an upright position at all times is not necessary and may not always be feasible or comfortable for the client. This rigid requirement is not part of the standard care protocol for managing swallowing difficulties.
Mr. N is a client who entered the hospital with a diagnosis of diabetic ketoacidosis. The nurse enters his room to check his vital signs and finds him breathing at a rate of 32 times per minute; his respirations are deep and regular. Which type of respiratory pattern is Mr. N most likely exhibiting?
- A. Kussmaul respirations
- B. Cheyne-Stokes respirations
- C. Biot's respirations
- D. Cluster breathing
Correct Answer: A
Rationale: Mr. N is most likely exhibiting Kussmaul respirations. Kussmaul respirations are a form of hyperventilation associated with conditions like metabolic acidosis. They are characterized by rapid, regular, and deep breathing. This type of respiratory pattern helps the body compensate for metabolic acidosis by attempting to blow off excess carbon dioxide. This pattern is different from Cheyne-Stokes respirations (choice B), which are characterized by alternating periods of deep, rapid breathing followed by apnea. Biot's respirations (choice C) are characterized by groups of quick, shallow inspirations followed by irregular periods of apnea, and Cluster breathing (choice D) involves clusters of breaths followed by periods of apnea, often seen in patients with brain injury or neurological conditions.
Mrs. F has been diagnosed with hyperparathyroidism. Which of the following complications is Mrs. F at highest risk of developing?
- A. Hyponatremia
- B. Hypocalcemia
- C. Hypermagnesemia
- D. Hypercalcemia
Correct Answer: D
Rationale: The parathyroid glands regulate calcium, vitamin D, and phosphorus in the body. Hyperparathyroidism leads to excessive production of parathyroid hormone, causing the release of calcium from bones into the bloodstream, resulting in elevated blood calcium levels, known as hypercalcemia. This puts individuals at risk of developing complications such as kidney stones, bone pain, osteoporosis, and neuropsychiatric symptoms. The other options, hyponatremia, hypocalcemia, and hypermagnesemia, are not directly associated with hyperparathyroidism. Hyponatremia is low sodium levels in the blood, hypocalcemia is low calcium levels, and hypermagnesemia is high magnesium levels, which are not typically seen in hyperparathyroidism.
A 58-year-old client is being tested for rheumatoid arthritis. Her physician orders an erythrocyte sedimentation rate (ESR). Which of the following results is most likely to be associated with arthritis?
- A. 5 mm/hr
- B. 12 mm/hr
- C. 28 mm/hr
- D. 40 mm/hr
Correct Answer: D
Rationale: The erythrocyte sedimentation rate (ESR) measures levels of inflammation in the body. Elevated ESR levels are commonly seen in autoimmune conditions like rheumatoid arthritis due to the presence of inflammation. In women over 50 years old, a normal ESR is typically below 30 mm/hr. Therefore, a result of 40 mm/hr is more indicative of arthritis in a 58-year-old individual. Choices A, B, and C are below the normal ESR range for a woman of this age and would not be as strongly associated with arthritis.
