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.

The nurse is teaching a client the proper technique for using a cane. Which statements should the nurse include in the teaching? Select all that apply.
- A. Hold the cane on the affected side.
- B. Hold the cane on the unaffected side.

A client has started sweating profusely due to intense heat. His overall luid volume is low and he has developed electrolyte imbalance. This client is most likely suffering from:
- A. Malignant hyperthermia
- B. Heat exhaustion
- C. Heat stroke
- D. Heat cramps
Correct Answer: B
Rationale: Heat exhaustion occurs when a person has enough diaphoresis that he becomes dehydrated. Intense sweating can cause both luid and electrolyte imbalances. Untreated heat exhaustion canlead to heat stroke, which results in organ damage, loss of consciousness, or death.
A client with adrenal insufficiency has a potassium level of 7.2 mEq/L. Which of the following signs or symptoms might the client exhibit with this result?
- A. Peaked T waves on the ECG
- B. Muscle spasms
- C. Constipation
- D. A prominent U wave on the ECG
Correct Answer: A
Rationale: A client with hyperkalemia may exhibit peaked T waves on an electrocardiogram. This manifestation is an early sign of high potassium levels, but diagnosis should not be based on this aspect alone. Untreated, hyperkalemia can lead to progressively worsening cardiac instability. Muscle spasms (Choice B) are more commonly associated with hypocalcemia. Constipation (Choice C) is not a typical sign of hyperkalemia. A prominent U wave on the ECG (Choice D) is associated with hypokalemia, not hyperkalemia.
A nurse is caring for a 3-day old infant who needs an exchange transfusion. Which of the following statements is appropriate for teaching the child's parents about this procedure?
- A. The registered nurse will be performing the procedure
- B. The procedure takes approximately 1 ? hours.
- C. The nurse will draw out 250cc of blood and then immediately replace it with 250cc
- D. The infant will continue to receive phototherapy during the procedure.
Correct Answer: B
Rationale: : An exchange transfusion is a method of controlling high bilirubin levels in infants when traditional phototherapy is unsuccessful. During an exchange transfusion, the physician removes 5-10 cc of blood and then replaces it with donor blood. The parents of this infant should know that the procedure is always performed by a physician and will take approximately 1 ½ hours to complete.
Which of the following conditions increases a client's risk of aspiration of stomach contents?
- A. A client is in restraints
- B. A client has a scaphoid abdomen
- C. A client is lying prone
- D. More than one answer is correct
Correct Answer: A
Rationale: A client in restraints is at an increased risk of aspiration of stomach contents. When a client is restrained, they may be unable to effectively move or turn their body if they begin to vomit, which can lead to aspiration. This lack of mobility can hinder their ability to protect their airway. On the other hand, a scaphoid abdomen, which is sunken or hollowed, is not a direct risk factor for aspiration. Additionally, lying prone, facing downward, does not necessarily increase the risk of aspiration, as aspiration is more likely when lying supine (facing upward). Therefore, the correct answer is that a client is in restraints.
