Nokea
Common symptoms of a fever include
- A. Muscle aches
- B. Sleepiness
- C. Slow movements
- D. Nausea
Correct Answer: A
Rationale: The correct answer is A: Muscle aches. Fever often triggers muscle aches as the body's temperature rises, leading to muscle fatigue and soreness. Sleepiness (B) can occur due to the body's increased energy expenditure during a fever. Slow movements (C) are not a common symptom of fever unless accompanied by muscle aches. Nausea (D) is more commonly associated with gastrointestinal issues rather than fever symptoms.

Signs and symptoms of a fecal impaction include the following:
- A. Urgency and black stools
- B. Urination and flatus
- C. Bleeding and itching
- D. Abdominal cramps and vomiting
Correct Answer: D
Rationale: The correct answer is D: Abdominal cramps and vomiting. Fecal impaction causes a blockage in the colon, leading to symptoms like abdominal cramps due to increased pressure and vomiting from the body's attempt to expel the blockage. Urgency and black stools (Choice A) are more indicative of gastrointestinal bleeding. Urination and flatus (Choice B) are not typically associated with fecal impaction. Bleeding and itching (Choice C) are more commonly seen in conditions like hemorrhoids or anal fissures.
Which of the following is a reason that people are at greater risk for infection as they get older?
- A. As people age
- B. their immune systems become stronger.
- C. Elderly people are hospitalized more often.
- D. Older people recover from illness more quickly.
Correct Answer: B
Rationale: Correct Answer: B
Rationale:
1. As people age, their immune systems naturally weaken, making them more susceptible to infections.
2. With age, the immune system's ability to respond to pathogens decreases, leading to an increased risk of infections.
3. Older individuals often have a reduced production of immune cells and antibodies, further compromising their immune response.
4. Conversely, choices A, C, and D do not directly address the physiological changes in the immune system associated with aging, making them incorrect.
You are monitoring the cardiac rhythm of your 60-year-old female patient with shortness of breath when you note the presence of a possible first-degree atrioventricular block in lead II on the EKG. Which of the following electrocardiogram abnormalities makes you think there is a first-degree AV block present?
- A. There are more than one P wave for each QRS complex
- B. A P-R interval greater than five small boxes (0.20 seconds) wide on the electrocardiogram tracing
- C. The P-R intervals become progressively longer until a QRS complex is dropped altogether
- D. The P waves are present but bear no relationship to the QRS complexes
Correct Answer: B
Rationale: The correct answer is B: A P-R interval greater than five small boxes (0.20 seconds) wide on the electrocardiogram tracing. In first-degree AV block, there is a delay in the conduction of the electrical impulse from the atria to the ventricles, resulting in a prolonged P-R interval. This delay causes the P-R interval to be longer than usual, typically greater than 0.20 seconds. This is indicative of the conduction abnormality seen in first-degree AV block.
Incorrect Choices:
A: There are more than one P wave for each QRS complex - This describes a condition known as atrial fibrillation where multiple P waves are present without a consistent relationship to the QRS complexes.
C: The P-R intervals become progressively longer until a QRS complex is dropped altogether - This describes a Mobitz type II second-degree AV block where there is a sudden drop of a QRS complex without a prior lengthening of the P-R interval.
The nurse is measuring the client's urine output and straining the urine to assess for stones. Which of the following should the nurse record as objective data?
- A. The client reports abdominal pain
- B. The client's urine output was 450 ML
- C. The client states, 'I didn't see any stones in my urine.'
- D. The client states, 'I feel like I have passed a stone.'
Correct Answer: B
Rationale: Objective data is measurable and observable, such as urine output volume.
Pediculosis causes symptoms such as
- A. Itching and rashes
- B. Acne and lesions
- C. Cuts and abrasions
- D. Boils and abscesses
Correct Answer: A
Rationale: The correct answer is A: Itching and rashes. Pediculosis is a condition caused by infestation of lice. Lice bites can lead to itching and skin irritation, resulting in rashes. Other choices like B: Acne and lesions, C: Cuts and abrasions, and D: Boils and abscesses are not typically associated with pediculosis. Acne is caused by blocked hair follicles, cuts and abrasions are physical injuries, and boils and abscesses are usually caused by bacterial infections. Therefore, the symptoms of itching and rashes are the most characteristic of pediculosis.
