The MOST significant contributory factor to the development of lung cancer is ________.
- A. being a cigarette smoker
- B. belonging to the male sex
- C. Being extremely obese
- D. age over 4 0years
Correct Answer: A
Rationale: The most significant contributory factor to the development of lung cancer is being a cigarette smoker. Cigarette smoking is directly linked to approximately 85% of lung cancer cases. The harmful substances in tobacco smoke, such as carcinogens, damage the cells in the lungs, leading to the development of cancer over time. Smokers are at a significantly higher risk of developing lung cancer compared to non-smokers. Therefore, being a cigarette smoker is the primary and most influential risk factor for developing lung cancer.

A woman in active labor experiences frequent and intense uterine contractions with minimal rest intervals, leading to maternal fatigue and decreased fetal oxygenation. What maternal condition should the nurse assess for that may contribute to this abnormal labor pattern?
- A. Maternal dehydration
- B. Uterine hyperstimulation
- C. Pelvic outlet obstruction
- D. Maternal exhaustion
Correct Answer: B
Rationale: Uterine hyperstimulation is a condition in which the uterus contracts too frequently or too intensely, leading to decreased blood flow and oxygenation to the placenta. This can result in maternal fatigue and decreased fetal oxygenation due to the lack of sufficient rest intervals between contractions. Uterine hyperstimulation can be caused by factors such as the use of synthetic oxytocin (Pitocin) to induce or augment labor, uterine abnormalities, or maternal conditions like pre-eclampsia. It is important for the nurse to assess for uterine hyperstimulation in a woman experiencing frequent and intense contractions to intervene promptly and prevent adverse outcomes for both the mother and the baby.
A patient presents with urinary frequency, urgency, dysuria, and suprapubic pain. Urinalysis reveals pyuria and bacteriuria. Which of the following conditions is most likely?
- A. Acute glomerulonephritis
- B. Chronic kidney disease
- C. Urinary tract infection (UTI)
- D. Renal calculi
Correct Answer: C
Rationale: The patient's presentation of urinary frequency, urgency, dysuria, and suprapubic pain along with the urinalysis findings of pyuria (pus in the urine) and bacteriuria (bacteria in the urine) are highly suggestive of a urinary tract infection (UTI). UTIs are one of the most common types of bacterial infections seen in clinical practice. The symptoms described are classic for a lower urinary tract infection. The presence of pyuria and bacteriuria on urinalysis further supports the diagnosis of a UTI. Acute glomerulonephritis typically presents with hematuria, proteinuria, hypertension, and edema. Chronic kidney disease is often asymptomatic in early stages and presents with symptoms like fatigue, edema, and changes in urination later on. Renal calculi are associated with severe colicky flank pain that can radiate to the groin, and they may present with
Nurses may be privy to very personal information of patients and should make every effort to make it confidential, otherwise she can be charged of ______.
- A. negligence
- B. invasion of privacy
- C. malpractice
- D. defamation
Correct Answer: B
Rationale: Nurses are bound by strict confidentiality and privacy regulations in their profession. If a nurse fails to keep a patient's personal information confidential and discloses it without authorization, they can be charged with invasion of privacy. Invasion of privacy is the wrongful intrusion into a person's private affairs without their consent, and it is a serious violation of ethical and legal standards in healthcare. Nurses must always prioritize patient confidentiality to maintain trust and uphold ethical standards in their practice.
A patient presents with redness, pain, and photophobia in the left eye. Slit-lamp examination reveals ciliary injection, corneal edema, and a mid-dilated pupil with fixed reaction to light. Which of the following conditions is most likely responsible for this presentation?
- A. Anterior uveitis
- B. Acute angle-closure glaucoma
- C. Endophthalmitis
- D. Corneal abrasion
Correct Answer: A
Rationale: The presentation described is consistent with anterior uveitis. Anterior uveitis involves inflammation of the iris and ciliary body. Patients typically present with symptoms such as redness, pain, photophobia, and blurred vision. The slit-lamp examination findings of ciliary injection (redness and dilation of blood vessels in the iris and ciliary body), corneal edema, and a mid-dilated pupil with a fixed reaction to light (due to ciliary muscle spasm causing decreased accommodation) are characteristic of anterior uveitis. This condition is often idiopathic but can be associated with various systemic diseases like ankylosing spondylitis, inflammatory bowel disease, and other autoimmune disorders. Treatment involves addressing the inflammation with topical corticosteroids and, in some cases, cycloplegic agents to reduce pain and inflammation.
A patient presents with polyuria, polydipsia, and polyphagia. Laboratory tests reveal hyperglycemia and glycosuria. Which endocrine disorder is most likely responsible for these symptoms?
- A. Hyperthyroidism
- B. Hypothyroidism
- C. Diabetes mellitus
- D. Cushing's syndrome
Correct Answer: C
Rationale: The symptoms of polyuria (excessive urination), polydipsia (excessive thirst), and polyphagia (excessive hunger) are classic signs of diabetes mellitus. In this case, the presence of hyperglycemia (high blood sugar) and glycosuria (glucose in the urine) further support the diagnosis of diabetes mellitus. Insulin deficiency or resistance in diabetes leads to impaired glucose utilization and excessive glucose in the bloodstream, causing the classic symptoms observed in the patient. Hyperthyroidism, hypothyroidism, and Cushing's syndrome do not typically present with the hallmark symptoms of polyuria, polydipsia, and polyphagia associated with uncontrolled diabetes mellitus.
