A patient presents with a blood pH of 7.29, bicarbonate (HCC) level of 25 mmol, and partial pressure of carbon dioxide (PaCO2) of 55 mmHg Which cause is consistent with these lab values?
Shallow and decreased breathing secondary to COPD
Hyperventilation secondary to a panic attack
Increased renal HCO2 excretion due to kidney disease
Excessive H ion loss due to severe vomiting
The Correct Answer is A
A. Shallow and decreased breathing secondary to COPD: The lab values indicate respiratory acidosis, which is characterized by a low pH (acidic), normal bicarbonate levels, and elevated PaCO2. This is consistent with hypoventilation, often seen in conditions like COPD, where shallow breathing leads to CO2 retention.
B. Hyperventilation secondary to a panic attack: Hyperventilation would cause respiratory alkalosis, not acidosis, characterized by a high pH and low PaCO2.
C. Increased renal HCO3 excretion due to kidney disease: This would lead to metabolic acidosis, not respiratory acidosis, and would typically be associated with a low bicarbonate level.
D. Excessive H+ ion loss due to severe vomiting: Severe vomiting causes metabolic alkalosis due to loss of H+ ions, not respiratory acidosis.

Correct Answer is ["B","E"]
Explanation
A. Menorrhagia: This refers to heavy menstrual bleeding, which is not typical in Turner's syndrome due to the absence of menstruation (primary amenorrhea).
B. Barrel chest: Individuals with Turner's syndrome often have a broad chest, which can be described as a "barrel chest" due to the increased distance between the nipples and the relative short stature.
C. Anomalous auricles: While some individuals with Turner's syndrome might have minor ear abnormalities, this is not a characteristic feature.
D. Cervical polyps: These are not specifically associated with Turner's syndrome.
E. Broad chest: A broad chest is a common physical characteristic in individuals with Turner's syndrome, along with a short stature and other physical anomalies.
Correct Answer is ["B","F"]
Explanation
A. Contaminated water: This is not a primary mode of transmission for N. gonorrhoeae.
B. Sexual contact: Neisseria gonorrhoeae primarily spreads through sexual contact, including vaginal, anal, and oral sex.
C. Inhalation: This is not a method of transmission for gonorrhea.
D. Undercooked meat: This does not relate to N. gonorrhoeae transmission.
E. Saliva: Although oral transmission can occur, saliva alone is not a primary method of spreading N. gonorrhoeae.
F. Childbirth: N. gonorrhoeae can be transmitted from an infected mother to her baby during childbirth, leading to neonatal conjunctivitis.
