Is it true that Hepatitis C virus (HCV) can be spread through hugging, sneezing, coughing, sharing eating utensils, and other forms of casual contact?
- A. TRUE
- B. FALSE
Correct Answer: B
Rationale: False. HCV is not spread through casual contact such as hugging, sneezing, or sharing eating utensils. The correct modes of transmission for HCV include direct contact with human blood through blood transfusions, improperly sterilized needles and syringes, needle sharing, or occasionally through sexual contact. Therefore, the statement is false, making 'False' the correct answer. Choices A, C, and D are incorrect as they do not accurately reflect the mode of transmission of HCV.

A client is admitted to a nursing unit with a remittent fever. Which statement best describes this pattern of fever?
- A. A fever that spikes and then lowers without returning to normal
- B. A fever that lasts 2 days followed by normal temperature for 2 days, followed by fever again
- C. A fever that lasts 2 days followed by normal temperature for 12 hours, followed by fever again
- D. A persistent fever that has lasted over 24 hours
Correct Answer: A
Rationale: A remittent fever is characterized by temperature fluctuations where the fever spikes and then lowers but does not return to normal temperature. Option A best describes this pattern of fever. Option B describes a pattern of fever known as a biphasic fever, where the fever alternates between days of fever and normal temperature. Option C describes a pattern of fever that is more indicative of an intermittent fever, where the fever lasts for a specific duration followed by an interval of normal temperature. Option D does not accurately describe a remittent fever, as it suggests a persistent fever that has lasted over 24 hours, which is not specific to the remittent pattern.
A client must use a non-rebreathing oxygen mask. Which of the following statements is true regarding this type of mask?
- A. A non-rebreather can provide an FiO2 of 40%.
- B. A client should breathe through his or her mouth when using a non-rebreather.
- C. A non-rebreather offers a reservoir from which the client inhales.
- D. The mask of a non-rebreather should be changed every 3 hours.
Correct Answer: A
Rationale: A non-rebreather mask is used for supplemental oxygen delivery for clients experiencing breathing difficulties. The non-rebreather mask includes a one-way valve that allows exhaled air to escape, preventing the rebreathing of carbon dioxide. The client inhales oxygenated air from a reservoir bag attached to the mask, providing high-concentration oxygen therapy. A non-rebreather mask can deliver FiO2 levels of up to 90%, making it an effective intervention for clients requiring high oxygen concentrations. Therefore, the statement that 'A non-rebreather can provide an FiO2 of 40%' is correct. Choices B, C, and D are incorrect because clients should breathe through their nose and mouth, the mask offers a reservoir for inhaling oxygen, and the mask should be assessed and potentially replaced if soiled or damaged, not routinely changed every 3 hours.
Which of these statements best describes the characteristics of an effective reward feedback system?
- A. Specific feedback is given as close to the event as possible
- B. Staff is given feedback in equal amounts over time
- C. Positive statements precede negative statements
- D. Performance goals should be higher than what is attainable
Correct Answer: A
Rationale: The correct answer is that specific feedback should be given as close to the event as possible in an effective reward feedback system. This is important because feedback is most useful when provided immediately. Giving feedback promptly reinforces positive behavior and helps in modifying problem behaviors. Providing feedback close to the event helps in ensuring that standards are clearly understood and can be met. Choices B, C, and D are incorrect because staff should not be given feedback in equal amounts over time, positive statements do not necessarily have to precede negative statements, and setting performance goals higher than what is attainable can lead to demotivation and decreased performance.
A patient with peripheral vascular disease is receiving discharge instructions. Which of the following information should be included?
- A. Walk barefoot whenever possible.
- B. Use a heating pad to keep feet warm.
- C. Avoid crossing the legs.
- D. Use antibacterial ointment to treat skin lesions prone to infection.
Correct Answer: C
Rationale: Patients with peripheral vascular disease should be advised to avoid crossing their legs as this can impede blood flow. Peripheral vascular disease, also known as arteriosclerosis obliterans, is primarily caused by atherosclerosis. Atherosclerosis results in the gradual progression of arterial occlusion due to the formation of atheromas. Crossed legs can further restrict blood flow, exacerbating the condition. Walking barefoot should be discouraged to prevent potential injuries to the feet. Using a heating pad can lead to burns and should be avoided to prevent thermal injuries. While using antibacterial ointment for skin lesions may be beneficial, it is not the priority instruction for patients with peripheral vascular disease.
A patient in the cardiac unit is concerned about the risk factors associated with atherosclerosis. Which of the following are hereditary risk factors for developing atherosclerosis?
- A. Family history of heart disease
- B. Overweight
- C. Smoking
- D. Age
Correct Answer: A
Rationale: A family history of heart disease is an inherited risk factor for developing atherosclerosis. This factor is not modifiable through lifestyle changes. Studies have shown that having a first-degree relative with heart disease significantly increases the individual's risk of developing atherosclerosis. Overweight, smoking, and age are not hereditary risk factors for atherosclerosis. Overweight and smoking are lifestyle-related risk factors, while age is a non-modifiable risk factor that increases with time but is not directly inherited.
