Which of the following dental conditions is characterized by the abnormal wearing away of tooth structure due to factors such as bruxism or acidic erosion?
- A. Dental caries
- B. Attrition
- C. Abrasion
- D. Erosion
Correct Answer: B
Rationale: Attrition is the dental condition characterized by the abnormal wearing away of tooth structure due to factors such as bruxism (grinding or clenching of teeth) or acidic erosion. Bruxism can cause tooth-to-tooth contact that leads to the wearing down of the tooth enamel and eventually can affect deeper layers of the tooth. Acidic erosion, on the other hand, is caused by the direct contact of teeth with acidic substances, which can lead to the gradual loss of tooth structure over time. Dental caries refers to tooth decay caused by bacteria, abrasion involves wearing away of tooth structure due to external factors like improper brushing habits, and erosion specifically relates to the loss of tooth structure caused by acidic substances.

Which of the following is a common complication of untreated gonorrhea or chlamydia infection in women?
- A. Cervical dysplasia
- B. Ectopic pregnancy
- C. Urinary incontinence
- D. Pelvic organ prolapse
Correct Answer: B
Rationale: Ectopic pregnancy is a common complication of untreated gonorrhea or chlamydia infection in women. This occurs when a fertilized egg implants and grows outside the uterus, typically in one of the fallopian tubes. Both gonorrhea and chlamydia can lead to scarring of the fallopian tubes due to untreated inflammation and infection. This scarring may obstruct the fallopian tubes, making it difficult for the fertilized egg to travel to the uterus for implantation. As a result, the egg may implant and grow in the fallopian tube, leading to an ectopic pregnancy. Ectopic pregnancies are dangerous and can result in serious complications for the woman, including rupture of the fallopian tube, internal bleeding, and potentially life-threatening situations. It is crucial to seek prompt treatment for gonorrhea and chlamydia to prevent such severe outcomes.
A patient is going for a coronary arterial by-pass graft (CABG) due to a 4 blocked arterial blood vessels. A surgical team has been formed with the cardiac surgeon as the head. Who is the member of the health team that prepares the pre-operative orders for the patient?
- A. Cardiologist
- B. Surgeon
- C. Anesthesiologist
- D. Medical Internist
Correct Answer: C
Rationale: The member of the health team responsible for preparing pre-operative orders for a patient undergoing surgery, such as a coronary arterial bypass graft (CABG), is typically the anesthesiologist. Anesthesiologists are specialized physicians who are trained to administer anesthesia and manage the patient's well-being during surgery. They are responsible for assessing the patient's medical history, determining the appropriate anesthesia plan, and prescribing pre-operative medications. Cardiologists focus on diagnosing and treating heart conditions, surgeons perform the actual surgical procedure, and medical internists specialize in the diagnosis and non-surgical treatment of internal diseases. The anesthesiologist plays a crucial role in ensuring the safety and comfort of the patient before, during, and after surgery.
Given her problems of hyper vigilance and worry that something terrible will happen to her child, nursing interventions should be aimed at addressing her needs for _______.
- A. Love and belongingness
- B. psychological security
- C. biological integrity
- D. self-esteem
Correct Answer: B
Rationale: Nursing interventions should be aimed at addressing the mother's needs for psychological security. Hyper vigilance and excessive worry about her child's safety indicate a lack of security in her mind.

Establishing trust and building a therapeutic relationship can also contribute to enhancing the mother's psychological security and well-being.
A postpartum client exhibits signs of postpartum psychosis, including hallucinations, delusions, and disorganized behavior. Which nursing intervention is most appropriate?
- A. Administering antipsychotic medication as ordered
- B. Encouraging the client to participate in group therapy sessions
- C. Providing education on coping skills and stress management
- D. Notifying the healthcare provider immediately
Correct Answer: D
Rationale: When a postpartum client exhibits signs of postpartum psychosis such as hallucinations, delusions, and disorganized behavior, it is crucial to involve the healthcare provider immediately. Postpartum psychosis is a psychiatric emergency that requires prompt assessment and intervention by mental health professionals. The healthcare provider can determine the appropriate course of action, which may include hospitalization, medication management, and specialized psychiatric care. Delaying notification can lead to serious consequences for both the client and her infant, so timely intervention is essential in managing postpartum psychosis.
A nurse is preparing to perform a wound irrigation procedure for a patient with a contaminated wound. What solution should the nurse use for wound irrigation?
- A. Sterile water
- B. Normal saline
- C. Hydrogen peroxide
- D. Betadine solution
Correct Answer: B
Rationale: Normal saline is the preferred solution for wound irrigation because it is isotonic and will not damage healthy tissue or delay wound healing. It helps to remove debris and pathogens from the wound, promoting a clean environment for healing. Sterile water can be used if normal saline is not available, but it may cause cellular damage if used in large volumes. Hydrogen peroxide and Betadine solution are not recommended for wound irrigation as they can be cytotoxic to the tissues and interfere with the wound healing process. It's important for the nurse to use evidence-based practice and follow recommended guidelines to promote optimal wound healing outcomes.
