When assessing an individual with peripheral vascular disease, which clinical manifestation would indicate complete arterial obstruction in the lower left leg?
- A. Aching pain in the left calf.
- B. Burning pain in the left calf.
- C. Numbness and tingling in the left leg.
- D. Coldness of the left foot and ankle.
Correct Answer: D
Rationale: Coldness of the left foot and ankle is the correct clinical manifestation indicating complete arterial obstruction in the lower left leg. Complete arterial obstruction results in reduced blood flow, leading to decreased temperature in the affected area. Aching pain (Choice A) and burning pain (Choice B) are more commonly associated with partial obstructions or ischemia, while numbness and tingling (Choice C) can be indicative of nerve involvement or compromised circulation, but not specifically complete arterial obstruction. The coldness in the foot and ankle is a result of severely reduced blood flow, which impairs the delivery of oxygen and nutrients to the tissues in that area, leading to a lower temperature. This symptom is a critical indicator of a more severe blockage compared to the other options provided.

Which of the following is a common cause of acute kidney injury?
- A. Hypertension
- B. Dehydration
- C. Infection
- D. Hypotension
Correct Answer: C
Rationale: Infection is a common cause of acute kidney injury because when the body fights an infection, it activates the immune response, leading to inflammation. This inflammatory response can affect the kidneys and impair their function. While hypertension (choice A) is a risk factor for chronic kidney disease, it is not a direct cause of acute kidney injury. Dehydration (choice B) can lead to prerenal acute kidney injury due to decreased blood flow to the kidneys, but infection is a more common cause of acute kidney injury. Hypotension (choice D) can contribute to prerenal acute kidney injury, but it is not a direct cause like infection.
Which of the following assessments is the most important for a patient receiving IV potassium?
- A. Respiratory rate
- B. Heart rate
- C. Blood pressure
- D. Oxygen saturation
Correct Answer: C
Rationale: The most important assessment for a patient receiving IV potassium is monitoring blood pressure. IV potassium can cause significant changes in cardiac function, leading to adverse effects such as arrhythmias and cardiac arrest. While respiratory rate, heart rate, and oxygen saturation are important parameters to monitor in clinical practice, blood pressure takes precedence in patients receiving IV potassium due to its direct impact on cardiovascular function. Changes in blood pressure can be an early indicator of potassium-induced cardiac complications, making it crucial to monitor closely during administration.
What is the most common cause of urinary tract infections (UTIs)?
- A. Escherichia coli infection
- B. Staphylococcus aureus infection
- C. Pseudomonas aeruginosa infection
- D. Klebsiella pneumoniae infection
Correct Answer: A
Rationale: Escherichia coli is the most common cause of urinary tract infections (UTIs). It is responsible for the majority of UTIs, especially in women. E. coli is a normal inhabitant of the bowel and can enter the urinary tract through the urethra, leading to infection. Staphylococcus aureus, Pseudomonas aeruginosa, and Klebsiella pneumoniae are less common causes of UTIs compared to E. coli. Staphylococcus aureus typically causes skin and soft tissue infections, Pseudomonas aeruginosa is more commonly associated with healthcare-associated infections, and Klebsiella pneumoniae is known for causing pneumonia and other respiratory infections.
A 68-year-old client on day 2 after hip surgery has no cardiac history but reports having chest heaviness. The first nursing action should be to:
- A. Inquire about the onset, duration, severity, and precipitating factors of the heaviness.
- B. Administer oxygen via nasal cannula.
- C. Offer pain medication for the chest heaviness.
- D. Inform the physician of the chest heaviness.
Correct Answer: A
Rationale: The correct first nursing action when a client reports chest heaviness post-hip surgery is to gather more information through assessment. Inquiring about the onset, duration, severity, and precipitating factors of the heaviness is crucial to determine the cause. This approach helps the nurse to gather essential data to make an informed decision regarding the client's care. Administering oxygen (Choice B) may be indicated based on assessment findings, but it is crucial to assess first. Offering pain medication (Choice C) without further assessment is premature and may mask symptoms. Informing the physician (Choice D) should be done after a thorough assessment to provide comprehensive information for appropriate medical decision-making.
The adult client admitted to the post-anesthesia care unit (PACU) following abdominal surgery has a tympanic temperature of 94.6°F (34.8°C), a pulse rate of 88 beats/minute, a respiratory rate of 14 breaths/minute, and a blood pressure of 94/64 mmHg. Which action should the nurse implement?
- A. Take the client's temperature using another method.
- B. Raise the head of the bed to 60 to 90 degrees.
- C. Ask the client to cough and deep breathe.
- D. Check the blood pressure every five minutes for one hour.
Correct Answer: A
Rationale: Taking the client's temperature using another method is the most appropriate action in this situation. A tympanic temperature of 94.6°F (34.8°C) is abnormally low and may not reflect the true core body temperature accurately. By using an alternative method, such as oral or rectal temperature measurement, the nurse can obtain a more reliable temperature reading. Raising the head of the bed (Choice B) is not directly related to addressing the low temperature. Asking the client to cough and deep breathe (Choice C) may be beneficial for respiratory function but does not address the temperature concern. Checking the blood pressure every five minutes for one hour (Choice D) is not the priority when the initial focus should be on accurate temperature assessment.
