Which of the following is an example of a suffix?
- A. Broncho in bronchoscopy
- B. Rhino in rhinoplasty
- C. Neuro in neuropathy
- D. Scopy in endoscopy
Correct Answer: D
Rationale: The correct answer is D: Scopy in endoscopy. A suffix is a word part added to the end of a root word to modify its meaning. In this case, "scopy" is a suffix added to the root word "endo" to form the word "endoscopy," meaning visual examination within. Choices A, B, and C are all prefixes, not suffixes. Prefixes are word parts added to the beginning of a root word to modify its meaning. In choices A, B, and C, "broncho," "rhino," and "neuro" are all added to the root words "scopy," "plasty," and "pathy," respectively, to form new words.

When transferring a resident who has a weak side,
- A. The weaker side moves first
- B. The stronger side moves first
- C. The strong side and weak side move at the same time
- D. It does not matter which side moves first
Correct Answer: B
Rationale: The correct answer is B because when transferring a resident with a weak side, it is important to move the stronger side first to provide better support and stability. By moving the stronger side first, you can ensure proper weight distribution and reduce the risk of falls or injuries. This approach also helps prevent the weaker side from bearing too much weight or strain.
Choice A is incorrect because moving the weaker side first may compromise the resident's safety and stability. Choice C is incorrect as it can lead to imbalance and increase the risk of falls. Choice D is incorrect because the sequence of movement does matter to ensure a safe transfer for both the resident and the caregiver.
Which of the following medication types are used to decrease the workload of the heart by blocking sympathetic stimulation of receptors that work on the SA node and myocardial cells, thus decreasing the force of myocardial contraction and directly reducing a patient's heart rate?
- A. Alpha-adrenergic agents
- B. Beta-blockers
- C. Calcium-channel blockers
- D. Sodium-channel blockers
Correct Answer: B
Rationale: The correct answer is B: Beta-blockers. Beta-blockers decrease the workload of the heart by blocking the sympathetic stimulation of beta-adrenergic receptors in the heart. This action results in a decrease in heart rate and the force of myocardial contraction. By blocking these receptors, beta-blockers reduce the impact of adrenaline and other stress hormones on the heart, leading to a decrease in the heart's workload.
A: Alpha-adrenergic agents primarily work on alpha-adrenergic receptors and do not have the same effect on decreasing the workload of the heart.
C: Calcium-channel blockers work by blocking calcium channels in the heart and blood vessels, leading to vasodilation and decreased contractility of the heart. While they can reduce the heart's workload, they do not primarily target sympathetic stimulation of receptors working on the SA node and myocardial cells.
D: Sodium-channel blockers primarily affect the conduction of electrical impulses in the heart and are used for different purposes, such as
Erectile dysfunction is
- A. A normal change of aging
- B. Treated with medication
- C. Incurable
- D. An inflammation of the testes
Correct Answer: B
Rationale: The correct answer is B because erectile dysfunction is commonly treated with medication such as phosphodiesterase type 5 inhibitors. It is not a normal change of aging (A), as it can affect men of all ages. It is also not incurable (C), as there are various treatment options available. Additionally, erectile dysfunction is not related to inflammation of the testes (D), which is a separate medical condition. Therefore, the correct choice is B as it aligns with the standard treatment approach for erectile dysfunction.
A ______ lists the tasks that nursing assistants are permitted to perform as allowed by state or federal law.
- A. Procedure manual
- B. Cover letter
- C. Scope of practice
Correct Answer: C
Rationale: The correct answer is C, Scope of practice. A scope of practice outlines the tasks nursing assistants can legally perform. It is based on state or federal regulations and ensures safe and effective care. A procedure manual (A) provides instructions for specific tasks but doesn't define legal boundaries. A cover letter (B) is a document used in job applications and is unrelated to task permissions. Option D is incomplete and irrelevant to the question.
While conducting an EKG on your post-myocardial infarction patient, you note the presence of consistently wide QRS complexes greater than 120 ms in duration. What does this most likely indicate?
- A. An intraventricular conduction delay or right/left bundle branch block
- B. A complete heart block indicating no relationship between the atria and ventricles
- C. The patient is likely suffering from a myocardial infarction currently
- D. The patient has a congenital heart defect and should not require emergency care
Correct Answer: A
Rationale: The correct answer is A: An intraventricular conduction delay or right/left bundle branch block. Wide QRS complexes (>120 ms) suggest delayed ventricular depolarization, which can be caused by bundle branch blocks. In the context of a post-myocardial infarction patient, this is a common finding due to damage to the conduction system.
Summary:
B: A complete heart block is characterized by a lack of communication between the atria and ventricles, leading to a different EKG pattern.
C: Wide QRS complexes do not directly indicate a current myocardial infarction; other EKG changes would be seen.
D: Wide QRS complexes are not typically associated with congenital heart defects in this scenario, and emergency care may still be necessary.
