Correct Answer: B

Rationale: The correct answer is Teres major. The Rotator Cuff consists of Teres Minor, Infraspinatus, Supraspinatus, and Subscapularis muscles, not Teres major. Teres major is not part of the rotator cuff, so it cannot be considered as possibly being torn. The other choices, Teres minor, Supraspinatus, and Infraspinatus, are all part of the Rotator Cuff and could potentially be torn in this patient's case.

Correct Answer: C

Rationale: To confirm pregnancy, the presence of palpable fetal movement is a positive indicator. Palpable fetal movement is a certain sign of pregnancy, known as a fetal movement felt by the examiner. Amenorrhea is a presumptive sign of pregnancy as it is reported by the woman but is not confirmatory. Thinning of the cervix (Hegar sign) is a probable sign of pregnancy, which is not confirmatory. A positive result on a home urine test for pregnancy is also a probable indicator. However, a positive pregnancy test result can sometimes yield false-positive results due to various factors like medication, recent pregnancy, or errors in reading.

Correct Answer: B

Rationale: According to Erikson's theory of psychosocial development, infants struggle to establish a sense of basic trust rather than a sense of basic mistrust in their world, their caregivers, and themselves. If provided with consistent satisfying experiences that are delivered in a timely manner, infants come to rely on the fact that their needs are met and that, in turn, they will be able to tolerate some degree of frustration and discomfort until those needs are met. This sense of confidence is an early form of trust and provides the foundation for a healthy personality. Therefore, options A, C, and D are incorrect as they do not align with Erikson's theory that emphasizes the importance of infants trusting that their needs will be met.

Correct Answer: D

Rationale: The tissue that would receive the highest amount of cardiac output and thus the highest amount of a drug is the myocardium. Highly perfused tissues include vital organs like the brain, heart, kidneys, adrenal glands, and liver. The myocardium, being part of the heart, receives a significant amount of cardiac output. Choices A (skin) and B (adipose tissue) are poorly perfused tissues and would not receive high amounts of cardiac output. Choice C (skeletal muscle) is also less perfused compared to the myocardium.

Correct Answer: B

Rationale: An FHR of 160 beats/min in the first trimester of pregnancy is within the normal range, which is generally 120 to 160 beats/min. The appropriate action for the nurse in this situation is to document the findings. There is no need to notify the healthcare provider as this is a normal finding. Informing the client that the FHR is faster than normal may cause unnecessary anxiety, as it falls within the expected range. Waiting to recheck the FHR is not necessary since the rate is already within the normal range.
